Question

the electrons identified by quantum numbers 'n' and 'l'
options:-
a) n=4,l=1
b) n=4,l=0
c) n=3,l=2
d) n=3,l=1
please answer with explanation....

Answer 1

all options are correct.......

Answer 2

See , that I think so that
The value of l is from 0 to (n-1) then if
n = 1 then l = 0
n = 2 then l = 0,1
n = 3 then l = 0 , 1, 2
n = 4 then l = 0 ,1,2,3
And the particular value among these values are depend on the value of m ( magnetic quantum number)..
I think this is useful for you in some aspect ☆☆☆
