Question

how many electrons can be assigned to orbitals designated by the quantum numbers n = 6, ℓ = 2?

Answer 1

n=6, l=2, represent the 6f orbital,which contain maximum 14 electron, p subshell has 7 orbital according to (2l+1) rule, here l =2, so (2l+1)=2*2+1=5,each orbital contain two electrons, hence seven orbitals contain (7*5)=36 electrons
