This gives calcium an outer-shell electron configuration corresponding to that of beryllium and magnesium. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom and are more easily lost or shared than the core electrons. By convention, the ms=+12ms=+12 value is usually filled first.
