Question

what is the lowest value of n that allows g orbitals to exist

Answer 1

Lowest value of n will be 5 for which g orbital can exist
See in azimuthal quantum number if n= some integer say 1 then L= 0 to n-1
N=1 -----' L=0 MEANS ONLY 1 SUBSHELL
N=2 ------- L=0,1 MEANS ONLY 2 SUBSHELL
LIKE WISE
N=5 -----''' L=0,1,2,3,4 so here max value of L is 4 means g orbital can exist means g orbital can only exist when L is having value of 4

Answer 2

Answer:The lowest value of n that allows g orbitals to exist is 5.

Explanation:

n  Orbitals that are filled

1  s

2  s,p

3  s,p,d

4  s,p,d,f

5  s,p,d,f,g
