Electron configuration and spectroscopy give order to the periodic table because of thier properites. Electron configuration is the arrangment and number of electrons in an atom. As the number and arrangment of electrons goes up, it gives a numerical order to them. This allows for the table to first have organization.

Spectroscopy is the amount of light given off by atoms in different colors of the spectrum. These colors and thier positions give identity to the atom. This then sets structure for the periodic table for the different elements to be put into specific groups with specific properties shared by the group.

Zirconium was discovered by Martin Hienrich Klaproth, a German chemist, who was studing the mineral jargon (ZrSiO4). It was made into it pure form in 1824 by a man named Jons Jacob Berzelius. Since zirconium is very resistant to erosion, it is used in high performance machinery. And since it does not easily absorb neutrons it is also used in neuclear reactors.

Revised Question 2

Electron configuration and spectroscopy have facilitated the organization of the periodic table because it gives the table an order on which to follow. the electron configuration is a constant pattern that electron fit into when forming new atoms, and spectroscopy deals with the light givin off when those electrons become excited. Because both of those things are unchangeable variables, they can be used as a sense of order. The periodic table is constant because becuase both electron configuration and spectroscopy are constant.

Americcium was discovered in 1944 by Glenn T. Seaborg. He discovered it by bombarding plutonium with neutrons. Am241 is commonly used as a part of home smoke detectors due to its radioactivity and the ability of radiation to be easily detected.

Question #2 - Jp

Electron configuration has helped aid the periodic table by providing a more organized way of viewing the elements. It includes stuff such as orbitals and being able to find the atomic number of an element. Spectroscopy has further aided with the organization of the periodic table because it is a way for finding what an unknown substance is by measuring the strength, color, and/or measurements of the light through absorption or emission spectroscopy. And again, it has been further easily understood through the experiments that the scientists have done. As properties of different elements are similar, they were easily organized into the place they are at right now in the periodic table. Scientists develop elements through many ways, being purely by accident, through heavy machinery that costs millions and millions of dollars, and by studying the elements of the periodic table, which is just basically advancing in the research of the other scientists before him. A new element that was made not long ago is Ununseptium (with a better name to come later on). It is located between element 116 and element 118, itself being element 117. It's a long process as to how they developed it so I'm just going to simplify it to the best of my ability. 40 grams of adioactive element curium was put into target rods and lowered into the reactor then bombarded with neutrons for about 250 days. The result was 22 milligrams of nearly pure berkelium. It was then cooled and chemically purified for a total of 6 months. After, they used those materials, and others, to perform the Dubna experiment. This resulted in 6 events indicating the creation and subsequent decay of element 117.

Question #2

Electron configuration is the arrangement of electrons of an atom, a molecule, or other physical structure. The form of the periodic table is closely related to the electron configuration of the atoms of the elements. By knowing the electron configuration of an atom, a person can find the element they are searching for on the periodic table or vice versa. Niels Bohr was the first to propose in 1923 that the periodicity in the properties of the elements might be explained by the electronic structure of the atom. His proposals were based on the then current Bohr model of the atom, in which the electron shells were orbits at a fixed distance from the nucleus.
Each individual element has its own frequency of wavelengths. Spectroscopy was originally the study of the interaction between radiation and matter as a function of wavelength. Later the concept was expanded greatly to comprise any measurement of a quantity as a function of either wavelength or frequencey. When an individual chemical is burned, it gives off certain wavelenths of light. These wavelengths can be viewed with a spectroscope. By measuring the wavelenths, scientists are able to conceive which element they are studying.
A new element, Ununseptium, has recently been discovered. "Parts of the discovery were made inside a particle accelerator in Dubna, Russia, during the time frame 2009-2010, when new element 117 was synthesized in the collision of isotopes of calcium and radioactive element berkelium: in the reaction 249Bk + 48Ca. Other aspects of the discovery was made in the United States--at the Lawrence Livermore National Laboratory (Livermore, California), the Oak Ridge National Laboratory (Oakridge, Tennessee), Vanderbilt University (Nashville, Tennessee), and the University of Nevada (Las Vegas); and in Russia--at the Research Institute of Atomic Reactors (Dimitrovgrad). (Ununseptium (pronounced: oon-oon-SEPT-i-em) stands for "one-one-seven-ium")."- William Atkins (IWIRE)

Question 2

Electron Configuration: arrangement of electrons of an atom, a molecule, or other physical structure. It concerns the way electrons can be distributed in the orbital’s of the given system. Niels Bohr was the first to propose (1923) that the periodicity in the properties of the elements might be explained by the electronic structure of the atom.[5] His proposals were based on the then current Bohr model of the atom, in which the electron shells were orbits at a fixed distance from the nucleus. The following year, E. C. Stoner incorporated Sommerfeld's third quantum number into the description of electron shells, and correctly predicted the shell structure of sulfur to be 2.8.6.[6] However neither Bohr's system nor Stoner's could correctly describe the changes in atomic spectra in a magnetic field, which was also called the Zeeman effect. Spectroscopy: originally the study of the interaction between radiation and matter as a function of wavelength (λ). Absorption spectroscopy uses the range of the electromagnetic spectra in which a substance absorbs. This includes atomic absorption spectroscopy and various molecular techniques, such as infrared, ultraviolet-visible and microwave spectroscopy. Emission spectroscopy uses the range of electromagnetic spectra in which a substance radiates (emits). The substance first must absorb energy. This energy can be from a variety of sources, which determines the name of the subsequent emission, like luminescence. Molecular luminescence techniques include spectrofluorimetry. Scattering spectroscopy measures the amount of light that a substance scatters at certain wavelengths, incident angles, and polarization angles. One of the most useful applications of light scattering spectroscopy is Raman spectroscopy. Unobtainium: In engineering, fiction, or thought experiments, Unobtainium, which can be also spelled Unobtanium, is any extremely rare, costly, or physically impossible material, or (less commonly) device needed to fulfill a given design for a given application. The properties of any particular unobtainium depend on the intended use. For example, a pulley made of unobtainium might be massless and frictionless; however, if used in a nuclear rocket unobtainium would be light, strong at high temperatures, and resistant to radiation damage. The concept of unobtainium is often applied flippantly or humorously. Discovered by Marvenio Disanter at the University of Asgard in 20 BU. Atomic weight 310.065 (characteristic of naturally occurring isotopic mixture), atomic number 126, most common valence of 1 and 3. None of the three naturally occurring isotopes are stable nuclides. These are mass number 310, T½ 4.5 X 105 years, rel. at. mass 310.0508 (99.275%), mass number 312, T½ 7.1 X 104 years, , rel. at. mass 312.0439 (0.72 %), mass number 309, T½ 2.4 x 104 years, rel. at. mass 309.0409 (0.005 %). Occurrence in Skytopia crust 3.7 ppm. Mined as unobtanium ore. Main ores of commercial interest are Explosite (Uo6Si2O5), Boomite, (Uo5Al3Si9O24‧2 H2O), and Skystone (Uo3C23H30N11O4). Unobtanium is a deep green, lustrous, brittle, radioactive metal. It tarnishes rapidly in air, forming a layer of dark green oxide.

Electron Configuration - Is the way that electrons are found an atom. Each electronin an atom is described by four different quantum numbers. Three of these quantum numbers (n, 1, and ) represent the three deminsions to space in which an electron could be found. A wave function for an electron gives the probability of finding the electron at various points in space. A wave function for an electron in an atom is called an atomic orbital. The fourth quantum number (ms) refers to a certain magnetic quality called spin. An example: Electron configuration of an atom is such that electrons fill the shell nearest the nucleus before filling others further away.

Spectroscopy - Spectroscopy pertains to the dispersion of an object's light into its component colors (energies). By performing this disection and analysis of an object's light, astronomers can infer the physical properties of that object (like temperatures, mass, luminostiy and compostion).



New Element - the name is copernium, after the 16-th century Polish scientist Nicholas Copernicus. It is element 112 and ts symbol is Cn. Copernicium, a heavier relative of zinc, cadmuim and mercury, was first seen in 1996 by resesarchers at the Society for Heavy Ions Research in Darmstadt, Germany, after they bombarded a lead target with zinc ions.
It took the International Union of Pure and Applied Chemistry, which regulates nonmenclature, nearly 14 years to resolve disputes between the Germans and American researchers over who was first to produve the new element. In the March issue of the journal Pure and Applied Chemistry, the agency reported that the Germans had priority and were entitled to purpose a name.
Physicist Sigurd Hofmann, leader of the German team, said in a statement that it chose copernicium to "salute an influential scientist who didn't reciever any accolades in his own lifetime, and highlight the link between astronomy and the field of nuclear chemistry"
Copernicium was the first scientist to conclude that the planets of th solar system revolves around the sum rather than Earth.

We will never be able to attribute to a single individual the development of the basic building blocks of writing. Yet we do know the name of the man who devised the method of classifying the basic building blocks of matter, Dmitri Ivanovich Mendelee. Combination's of 26 letters make up every word in the English language. Similarly, all material things in the world are composed of different combination's of about 100 different elements. An element is a substance that cannot be broken down into simpler substances through ordinary chemistry--it is not destroyed by acids, for example, nor changed by electricity, light, or heat. Although philosophers in the ancient world had a rudimentary concept of elements, they were incorrect in identifying water, for example, as one. Today it is common knowledge that water is a compound, whose smallest unit is a molecule. Passing electricity through a molecule of water can separate it into two atoms of hydrogen and one atom of oxygen, each a separate element. The ancient concept of elements jibed with today's in noting that elements had characteristic properties. Just as people not only look different from each other but also interact differently with others, so elements have both physical and chemical properties. Some elements form shiny solids, for example, that react readily and sometimes violently with oxygen and water. The atoms of other elements form gases that scarcely interact with other elements. Scientist had identified over 60 elements by Mendeleev's time. (Today over 110 elements are known.) In Mendeleev's day the atom was considered the most basic particle of matter. The building blocks of atoms (electrons, protons, and neutrons) were discovered only later. What Mendeleev and chemists of his time could determine, however, was the atomic weight of each element: how heavy its atoms were in comparison to an atom of hydrogen, the lightest element. An overall understanding of how the elements are related to each other and why they exhibit their particular chemical and physical properties was slow in coming. Between 1868 and 1870, in the process of writing his book, The Principles of Chemistry, Mendeleev created a table or chart that listed the known elements according to increasing order of atomic weights. When he organized the table into horizontal rows, a pattern became apparent--but only if he left blanks in the table. If he did so, elements with similar chemical properties appeared at regular intervals--periodically--in vertical columns on the table.Mendeleev was bold enough to suggest that new elements not yet discovered would be found to fill the blank places. He even went so far as to predict the properties of the missing elements. Although many scientists greeted Mendeleev's first table with skepticism, its predictive value soon became clear. The discovery of gallium in 1875, of scandium in 1879, and of germanium in 1886 supported the idea underlying Mendeleev's table. Each of the new elements displayed properties that accorded with those Mendeleev had predicted, based on his realization that elements in the same column have similar chemical properties. The three new elements were respectively discovered by a French, a Scandinavian, and a German scientist, each of whom named the element in honor of his country or region. (Gallia is Latin for France.) Discovery of a new element had become a matter of national pride--the rare kind of science that people could read about in newspapers, and that even politicians would mention.Claiming a new element now meant not only identifying its unique chemical properties, but finding the atom's atomic weight so the element could be fitted into the right slot in the periodic table. For radioactive atoms that was a tough challenge. At first these atoms were isolated only in microscopic quantities. The straightforward way to identify them was not by their chemical properties at all, but by their radiations. Until the radioactive atoms could be sorted out with traditional chemistry, some scientists were reluctant to call them new elements.The value of the table gradually became clear, but not its meaning. Scientists soon recognized that the table's arrangement of elements in order of atomic weight was problematic. The atomic weight of the gas argon, which does not react readily with other elements, would place it in the same group as the chemically very active solids lithium and sodium. In 1913 British physicist Henry Moseley confirmed earlier suggestions that an element's chemical properties are only roughly related to its atomic weight (now known to be roughly equal to the number of protons plus neutrons in the nucleus). What really matters is the element's atomic number--the number of electrons its atom carries, which Moseley could measure with X-rays. Ever since, elements have been arranged on the periodic table according to their atomic numbers. The structure of the table reflects the particular arrangement of the electrons in each type of atom. Only with the development of quantum mechanics in the 1920s did scientists work out how the electrons arrange themselves to give the element its properties.
