Question number 2

Electron Configuration- It concerns the way electrons can be distributed in the orbitals of the given system . In 1932, Niels Bohr was the first to propose that the periodicity in the properties of the elements might be explained by the electronic structure of the atom. Bohr is responsible for the Bohr model. He got his basic idea off of both Aufbau's principle and Madelung's rule. Electron Configuration is also one of the best ways, for me, to find the location of and element in the periodic table. In electronic configuration, we have 4 blocks, which include, S-block, D-block, P-block, and F-Block.

Spectroscopy-was originally the study of the interaction between radiation and matter as a interaction betweeen wavelengths. It was originally the study of VISIBlE light. We look at a light source and it should break it up into different colors. If we use a flame as a light source then we can put a chemical into the flame and measure were the colors are. This is how we find what a sertant element is.

Ununpentium (Uup) was descovered in 2004. Although the Atomic mass, Electronegativity Density, Melting point, Boiling point, radius, & Ionic radius is still unknown we still have a way of sorting it and placing it in its own position on the periodic table. We have said the atomic number is 115. Its was created in California. It has a very short half- life and its almost no help for humans. BUT!! it still an element nun the less.
