Periodicity in atomic properties

Question

Which of the following species has highest ionisation energy ?

Moderate

A

Na⁺
B

Mg⁺
C

Na
D

Mg²⁺

Solution

Order of ionisation energy : $\frac{Na < {Mg}^{+}}{Isoelectronic} < \frac{{Na}^{+} < {Mg}^{2 +}}{Isoelectronic}$
$As (\frac{p}{e}) ↑ in isoelectronic species; ionisation energy increases.$
