1. Which one of the following configurations depicts an excited oxygen atom?
a. 1s2 2s2 2p2
b.1s2 2s2 2p2 3s2
c.1s2 2s2 2p1
d.1s2 2s2 2p4
a. is out of the question
c. is out of the questioin
I know d. is the ground state of oxygen
but how did they get 3s2 for b.?
It must be b. But I don't understand it.
2.Which of the following has the second largest Ionization energy?
a. ca
b. K
c.Ga
d. Ge
I am guessing it is K because after its first V.E. is gone the second one would be in the core, making it much harder to remove...
