In Germanium, if two electrons go from 1s go to 4p is it in its excited state?

It will certainly be in one of its excited states, yes, probably followed by an Auger cascade.

  • $\begingroup$ i thought an atom can only become excited when only ONE electron moves to a higher energy level? so why does it get excited when two electrons move up? $\endgroup$ – Jonie Mar 21 '14 at 1:53

    $\begingroup$ "Excited" means "higher energy state". Everything higher than the ground state is therefore considered excited. $\endgroup$ – tschoppi Mar 21 '14 at 12:29
  • $\begingroup$ en.wikipedia.org/wiki/Rydberg_atom "A Rydberg atom is an excited atom with one or more electrons that have a very high principal quantum number," $\endgroup$ – Uncle Al Mar 21 '14 at 22:52

    $\begingroup$ @Jonie: People commonly refer to such states as "doubly excited". $\endgroup$ – Aesin Jun 19 '14 at 0:39
