The set representing the correct order of the first ionisation potential is

A

`K gt Na gt Li`

B

`Be gt Mg gt Ca`

C

`B gt C gt N`

D

`Ge gt Si gt C`

Text Solution

Verified by Experts

The correct Answer is:
B
`IE_(1)` decreases down the group `2` elements.
Hence, `IE_(1)` order is `BE gt Mg gt Ca`.
