Question
The incorrect statement among the following is
✓
Answer
b
(b) $I.E.(II)$ of $Na$ is higher than that of $Mg$ because in case of $Na$, the second ${e^ - }$ has to be remove from the noble gas core while in case of $Mg$ removal of second ${e^ - }$ gives a noble gas core.
(b) $I.E.(II)$ of $Na$ is higher than that of $Mg$ because in case of $Na$, the second ${e^ - }$ has to be remove from the noble gas core while in case of $Mg$ removal of second ${e^ - }$ gives a noble gas core.
$Mg$ has high first ionisation potential than $Na$ because of its stable $n{s^2}$ configuration.
