Well, you gots an alkaline earth from the fifth Period...and so the valence electrons are #5s^(2)#...

Explanation:

And so for #Z=38# (from where did I get that number?) we gots 38 electrons to distribute....

#Sr:underbrace(1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(2)3d^(10)4p^(6))_"electronic configuation of krypton"5s^(2)#
