Question
The incorrect statement among the following is
- The first ionisation potential of
is less than the first ionisation potential of 
- The second ionisation potential of is greater than the second ionisation potential of
- The first ionisation potential of is less than the first ionisation potential of
- The third ionisation potential of is greater than the third ionisation potential of
is less than the first ionisation potential of is greater than the second ionisation potential of is less than the first ionisation potential of is greater than the third ionisation potential of The correct answer is: The second ionisation potential of is greater than the second ionisation potential of
I.E.(II) of is higher than that of because in case of , the second 
has to be remove from the noble gas core while in case of removal of second gives a noble gas core.
has high first ionisation potential than because of its stable 
configuration.
