For an element having only valence shell...

For an element having only valence shell electron, then which of the following ionisation energy difference will have the maximum value-

A

`IE_(2) - IE_(1)`

B

`IE_(3) - IE_(2)`

C

`IE_(3) - IE_(1)`

D

can't predict

Text Solution

Verified by Experts

The correct Answer is:
C
`IE_(3) gt IE_(2) gt IE_(1)` always, thus `IE_(3) - IE_(1)` will be maximum.
