Correct answer
D
Step-by-step explanation
(A) n = 3; l = 0; m = 0 ; 3s orbital
(B) n = 4; l = 0; m = 0 ; 4s orbital
(C) n = 3; l = 1; m = 0 ; 3p orbital
(D) n = 3; l = 2; m = 0 ; 3d orbital
As per Hund’s ruleo of energy is given by (n + l) value. If value of (n + l) remains same then energy is given by n only.
(B) n = 4; l = 0; m = 0 ; 4s orbital
(C) n = 3; l = 1; m = 0 ; 3p orbital
(D) n = 3; l = 2; m = 0 ; 3d orbital
As per Hund’s ruleo of energy is given by (n + l) value. If value of (n + l) remains same then energy is given by n only.
