Given below are two statements : Statement I : The metallic radius of \(\mathrm{Na}\) is \(1.86 \mathrm{~A}^{\circ}\) and the ionic radius of \(\mathrm{Na}^{+}\)is lesser than \(1.86 \mathrm{~A}^{\circ}\). Statement II : Ions are always smaller in size than the corresponding elements. In the light of the above statements, choose the correct answer from the options given below :
  1. Both Statement I and Statement II are false
  2. Statement I is incorrect but Statement II is true
  3. Both Statement I and Statement II are true
  4. Statement I is correct but Statement II is false

Solution

$\mathrm{r}_{\mathrm{Na}}>\mathrm{r}_{\mathrm{Na}^{+}}$
So, Statement (I) is correct but size of anions are greater than size of neutral atoms. So statement (II) is incorrect.
