Question

It is easy to form $Cs ^{+}$from Cs in comparison to $Na ^{+}$from Na . Why?

✓

Answer

On moving from up to down in group atomic size increases. Hence ionization enthalpy decreases. In comparison to Na , the size of Cs is more. Hence its ionization enthalpy is less in comparison to Na . Hence from this electrons are easily removed. Therefore it is easy to form $Cs ^{+}$from Cs in comparison to $Na ^{+}$from Na .
