Please give an answer for this question
Dear Student,
An electron will have highest energy in the set 4, 2, –1, 1+2
Reason: For this set value of n+l = 4+2 = 6 is maximum so its energy will be maximum
Where n = 4 ( Principal quantum number , l = Azumithal quantum number
a) 3, 2, ,1, 1+2
n =3 and l = 2
(n+l) = 3+ 2 = 5
c) 4,1,0,–1+2
n =4 and l = 1
(n+l) = 4+1 = 5
(D) 5,0,0,1+2
n =5 and l = 0
(n+l) = 5+0 = 5
Regards
