Question

$g$ orbital is possible if:

• A. $n=5$, $l=4$
• B. It will have 18 electrons
• C. It will have 9 types of orbitals
• D. It will have 22 electrons

Answer 1

Answer: (A), (B), (C)

The correct options are
A $n=5$, $l=4$
B It will have 9 types of orbitals
C It will have 18 electrons

(A) g orbital will have $n=5$, $l=4$.
(B) It has 18 electrons because $m=-4,-3,-2,-1,0,+1,+2,+3,+4$ i.e. 9 values. 9 orbitals therefore $9\times 2=18e$.
(C) Orbital will be of 9 types because m has 9 values given in (B).
(D) Is incorrect and explained in (B).
