Electron configuration is a complicated composition of atoms in oppossing elements. Electron configuration varies on element, consisting of the valence electrons. Niels Bohr in 1923 was the first know person to suggest that periodicity in the properties of the elements may have been explained by the electrons structure of the atom. The formation of the periodic table is similar to the structure of electron configuration of the atoms and the elements. the outer shell also determines major properties such as chemical, etc.

Spectroscopy uses the interaction of energy with an object to create data and perform an analysis or a spectrum. this so called "spectrum" can be used to obtain information about atomic and molecular energy levels and more. The infared absorbtion spectrum of a substance is sometimes called a molecular fingerprint which determines each elements placent of color using the infared absorbtion method.


RUTHERFORDIUM- and element that was recently discoverd in 1969 by a Dr. Albert Ghiorso and later named after the renouned chemist and physisyst Lord Rutherford. when the element was discoverd near Dubna, Russia the scientists lacked the proper equipment needed to accelerate neon ions, the Brekeley group, led by none other than Albert Ghiorso grinded atoms of californium with ions of carbon producing rutherfordium -257, -258, -259. credit for the discovery is still being tossed around by many people due to the fact that the finding was more a team effort than a solo operation.
