The second ionisation potential of $Mg$ is greater than the second ionisation potential of $Na$

Vedclass · Answer

(B) The correct answer is $(B)$.$1$. The first ionisation potential $(IE_1)$ of $Al$ $([Ne] 3s^2 3p^1)$ is less than $Mg$ $([Ne] 3s^2)$ because $Mg$ has a stable fully-filled $s$-orbital.$2$. The second ionisation potential $(IE_2)$ of $Na$ $([Ne] 3s^1 \rightarrow [Ne])$ is much higher than that of $Mg$ $([Ne] 3s^2 \rightarrow [Ne] 3s^1)$ because the second electron in $Na$ is removed from a stable noble gas core $([Ne])$.$3$. $IE_1$ of $Na$ is less than $Mg$ due to higher effective nuclear charge and stable configuration of $Mg$.$4$. The third ionisation potential $(IE_3)$ of $Mg$ is higher than $Al$ because the third electron in $Mg$ is removed from a stable noble gas core $([Ne])$,whereas in $Al$ it is removed from the $3s^2$ subshell.
