7. o A с D B Which quantum number is not allowed for the orbitals shown?...

Question

Question

Answer 1

Answer #1

7) option (C) is the answer because 2d orbitals do not exist. n = 2 for C orbital.

8) Configuration of Ga,

[Ar] 3d10 , 4s2 , 4p1

Last electron is in 4p1

n = 4 , l = 1 , m = -1 , s = +1/2

So acceptable set of quantum number is

n = 4 , l=1 , m = 1, s = -1/2 i.e. option (a)

Answer 2
