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

`K gt Nagt Li`

`Ge gt Si gt C`

`Be gt Mg gt Ca`

`B gt C gt N`

Text Solution

Verified by Experts

The correct Answer is:

In general, the ionization potential decrease on moving down the group due to increase in the number of shells:
`Be gt Mg gt Ca`
Other orders should be
`Li gt Na gt K`
`C gt Si gt Ge`
`N gt C gt B`

The correct order of the first ionisation potentials is

`Ne gt Cl gt P gt S gt Al gt Mg `

`Ne gt Cl gt P gt S gt Mg gt Al `

`Ne gt Cl gt S = P gt Mg gt Al `

`Ne gt Cl lt S gt P lt Al gt Mg`
