Hi, here we have to identify the element or ion in the given questions.
00:05
Now first we are given with the ground state for 6s and 6p orbitals here.
00:09
So now here, outer shell orbital configuration is 6 to 6p 4 here.
00:16
So there are total 6 valence electrons.
00:20
Now 6 valence electrons are present in group 16 elements and here n is equal to 6 so.
00:29
Period is 6.
00:33
So from here we can say that element is po, that is polonium.
00:45
Now next part is now here excited state is given that means that from 2s to 2p one electron has jumped but again valence electrons remain same.
01:03
So valence electrons are total.
01:05
4 here and 1 here, so 5 electrons.
01:09
Now 5 electrons are valence electrons in group 15 element and since it is 2s and 2p orbital that is n is equal to 2, so period is 2 for this and now element for this is nitrogen...
