The incorrect statement is
Solution
On moving down in a group ionisation energy decrease
<br/><br/>
$\therefore 1^{\text {st }}$ ionisation enthalpy order is $\mathrm{Li}>\mathrm{Na}>\mathrm{K}$
<br/><br/>
$\mathrm{Zn}$ has more ionisation energy as compared to Ga because of their pseudo inert gas configuration.
