Question

Valence electron of zinc atom possesses the quantum numbers n= 3, l = 2, m = +2 to -2 and s= +1/2 or -1/2.

• A. True
• B. False

Answer 1

The correct option is A True

The atomic number of Zn = 30 and the electronic configuration = $\left[Ar\right]3d^{10}4s^2$ . Thus the valence electron is in 3d orbital and has the quantum numbers as; n= 3, l = 2, m = +2 to -2 and s= +1/2 or -1/2.
