The second ionisation potential is

A

Less than the first ionisation potential

B

Equal to the first ionisation potential

C

Greater than the first ionisation potential

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
`IE_(1) lt IE_(2) lt IE_(3)`
Because with the removal of electron, number of protons remains same but number of electron decreases and so effective nuclear charge increases.
