Question

Alkali metals have low ionization energies. Give reason​

Answer 1

Answer:

The alkali metals have the lowest first ionisation energies in their respective periods of the periodic table because of their low effective nuclear charge and the ability to attain a noble gas configuration by losing just one electron.

Answer 2

Explanation:

Yes because alkali metals are larger in size. So they have less nuclear attraction towards electron and is easy to remove the electron from outer most shell so the alkali metals have low I.P values
