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.
