Fl 3 C/P 15 Quantum Numbers

Can someone explain to me this explanation of FL3 C/P 15. How do we determine Zn has 12 valence electrons?
Zinc (Z = 30) has a condensed electron configuration of [Ar] 4s2 3d10, with 12 valence electrons; two in the filled 4s** orbital and ten in the filled 3d orbital.
If it were Zn 2, would the configuration be [Ar]3d10? With 10 valence electrons?
Similarly, what do the formulas 2n2 and 4L 2 mean in this context? (Quantum numbers)
