`IE_(2) > IE_(1)` for a given element - why?

Text Solution

Verified by Experts

BY the removal of an electron from a neutral atom, a uni +ve ion is formed. In this uni +ve ion the number of protons are more that the number of electrons. Hence the nuclear attractions will be more in uni +ve ion. As a result of which more amount of energy is required to remove an electron from the uni +ve ion. Hence, 2nd IP values are always greater than first IP values.
