Which is the correct order of increasing energy of the listed orbitals in the atom of titanium.(At.no.Z=22)
Options
(a) 4s 3s 3p 3d
(b) 3s 3p 3d 4s
(c) 3s 3p 4s 3d
(d) 3s 4s 3p 3d
Correct Answer:
3s 3p 4s 3d
Explanation:
Ti(22):1s²2s²2p⁶3s² 3p⁶4s²3d²
.·. Order of increasing energy is 3s,3p, 4s, 3d.
