Question

if tha sum of [n+l]is 6 how many ele.s would have clock wise spin associated with this energy level

Answer 1

Explanation:

l can be minimum 0 and maximum n−1. Thus in those cases n=6 and n=4 (as n=3.5 is not acceptable). Thus possible combinations of n,l are n=6,l=0;n=5,l=1 and n=4,l=2. Thus only 3 such sub shells are possible . Thus answer is option A.
