Question

Is there removal of second electron difficult in alkali metals?

• A. Yes
• B. No
• C. Maybe
• D. Cannot say

Answer 1

Answer:

A. Yes

The first ionization enthalpy of alkali metals is the lowest among the elements in their respective periods and increases on moving down the Group. The second ionization enthalpies of the alkali metals are very high because by releasing an electron, ions require noble gas configuration, so removal of the second electron is difficult.
