Electron impact excitation of atomic and molecular systems has been a subject for both experimental and theoretical study since Franck and Hertz demonstrated the loss of energy of electrons passing through mercury vapour in 1914. Experimentally the great majority of studies on short-lived excited ...
However, an atom with an L shell also contains a K shell. In fact, the L shell will start filling up after the K shell is filled. This means that an atom with an L shell can support up to 10 electrons because of the presence of both the K and L shells. For example, lithium and...

Helium is not soluble in water. It is classified as an inert gas because the outermost electron orbital contains two electrons that don’t get close to other elements to form chemical bonds. It has a higher thermal conductivity than other gases apart from hydrogen. ...
