a) What is the lowest value of n that allows g orbitals to exist ?

(b) An electron is in one of the 3d orbitals. Give the possible values of n, l, and ${{m}_{1}}$ for this electron

# What is the lowest value of n that allows g orbitals to exist?

**prasanna**#1

**prasanna**#2

(a) For n; the values of l are 0,1,…(n -1)

.-. For n = 5; the values of l are 0,1,2,3,4

For l = 4; g subshell can exist. Hence lowest value of n = 5.

(b) When n = 3

l = 2 [Since it is in 3d subshell] oil = — 2, — 1,0, + 1, + 2
