Question
Given below are two statements :
Statement I: The second ionisation enthalpy of Na is larger than the corresponding ionisation enthalpy of Mg.
Statement II : The ionic radius of $O^{2 -}$ is larger than that of $F^{-}$.
In the light of the above statements, choose the correct answer from the options given below.
Options
A.Both statement I and statement II are true
B.Both statement I and statement II are false
C.Statement I is false but statement II is true
D.Statement I is true but statement II is false
Solution
$\ \mathbf{Na}^{+}$:- $1{\text{ }s}^{2}2{\text{ }s}^{2}2p^{6}$ (fully filled electronic configuration)
$${Mg}^{+}: - 1{\text{ }s}^{2}2{\text{ }s}^{2}2p^{6}3{\text{ }s}^{1} $$${IE}_{2}$ of $Na > {IE}_{2}$ of Mg
Size of $O^{2 -} > F^{-}$
