Question

Compare ionization energy of Lithium and sodium

Answer 1

Answer:

There are 11 protons in a sodium atom but only 3 in a lithium atom, so the nuclear charge is much greater. You might have expected a much larger ionisation energy in sodium, but offsetting the nuclear charge is a greater distance from the nucleus and more screening. ... That lowers the ionisation energy.

Answer 2

Explanation:

The ionization depends on its metallic nature.

The metals which is more reaction will ionize more ions. Then sodium is reactive than lithium, so sodium is more ionized metal than lithium.
