From EK Chem in chapter exam.
17) Which of the following species has an unpaired electron in its ground-state electronic configuration?
A)Ne
B)Ca+
C)Na+
D)O^2-
The answer is B, but I thought it was Na+, as Na (ground state) has an unpaired e-.
I can see that Ca+ has an unpaired electron, but it doesn't in the ground state, right?
