Q53 / 180 · NEET 2015 (Phase 2) · Chemistry

Which is the correct order of increasing energy of the listed orbitals in the atom of titanium?

(At. No. Z = 22)

A
3s 4s 3p 3d
B
4s 3s 3p 3d
C
3s 3p 3d 4s
Correct answer
D
3s 3p 4s 3d

Solution

$T i (22) = 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 4 s^{2} 3 d^{2}$
$\underset{n + l value}{energy level} = \underset{3 + 0 = 3}{3 s}, \underset{3 + 1 = 4}{3 p}, \underset{4 + 0 = 4}{4 s}, \underset{3 + 2 = 5}{3 d}$

Hence, the correct answer is option: 'D'.
