d) Zr2+

I have [Kr] 5s2  but it says that :Your answer contains an improperly or incompletely formatted hybridization

e) Po4+

I have [Xe] 6s2 4f14 5d10    but it says that :Your answer contains an improperly or incompletely formatted hybridization

Can someone please explain what I am doing wrong and what the correct answers would be?

Explanation / Answer

b) [Xe] 4f14 5d9 6s1

c) [Xe] 6s, 4f14, 5d10, 6p3

d) [Kr] 4d2

e) [Xe] 6s2 4f14 5d10

the electrons will come out first from the outrmost shells, 5..then 4...then 3 etc....despite of the fact (for example) like 6s is filled before 4d (this is just an example)
