For which of the following $2^{nd}$ I.E. $< 1^{st}$ I.E.

Options:

Answer:

Solution:

Ionization energy (I.E.) is the energy required to remove an electron. The second ionization energy ( $2^{n d}$ I.E.) is always greater than the first ionization energy ( $1^{s t}$ I.E.) because removing an electron from a positively charged ion requires more energy than removing it from a neutral atom. Therefore, $2^{n d}$ I.E. cannot be less than $1^{s t}$ I.E. for any element.
