The quantum number of six electrons are...

The quantum number of six electrons are given below ,Arrange them in order of increasing energies . If any of these combination has have the same energy lists :
(1) n-4 ,l=2 , `m_(1) = 2m_(1) = (1)/(2)`
(2) n=3 , l = 2, `m_(1) = 1 ,m_(s) = (1)/(2)`
`(3 ) n=4 , l = 1 , m_(1) = =0 m_(s ) = (1)/(2)`
`(4 ) n=3: l = 2 m_(1) = - 2 m_(s ) = - (1)/(2)`
`(5 ) n=3 , l = 1,m_(1) = - 1 m_(s ) = (1)/(2)`
`(6) n=4 , l = 1, m_(1) = 0 m_(s ) = (1)/(2)`

(1) l =2 so d and n= 4 so 4d subshell
(2) l=2 so d and n= 3 so 3d subshell
(3 ) l =1 so p and n=4 so 4p
(5 ) l =1 so p and n= 3 so 3p
(6) l =1 so p and n=4 so 4p
This 4d 3d , 3d 4p arrange as per energy than
(5) `3p (4 ) 3d = 2 (3d) lt (6) 4p = (3) 4p lt (1) 4d (5 ) lt (4) = (2) lt (6) = (3) lt (1) to` energy increases (2) ,(3) (4) and (6) has same energy .
