If Aufbau principle and Hund's rule were not followed

A

Ca would have been d-block element with zero dipole moment

B

Zn would have been s-block element

C

Ti would have been diamagnetic

D

`Fe^(3+)` ion would have 5 unpaired electrons

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
For no consideration of Aufbau principle nad Hund's rule, the electronic configuration `Ca(20),[Ar]3d^(2),Zn(30):[Ar]3d^(10)4s^(2)` (filling of 4s subshell after 3d subshell), `Ti(22), [Ar]3d^(2)` (both electrons paired up)
