In this problem, we're given the excited state electron configuration of an atom.
00:08
So we have our condensed version where we put our noble gas.
00:13
And then we have our s, which we see we only have one there.
00:18
We have completely filled de -oldrils.
00:21
And then we have four p electrons.
00:26
So here, first, let's note again, here we're missing one electron.
00:36
So if this were the ground state, we'd have two here.
00:41
And d is completely filled.
00:43
But p, one of these, and the ground state will be for us...
