Given below are two statements : Statement I : The metallic radius of (Na\mathrm{Na}) is (1.86  A∘\mathrm{~A}^{{}^{\circ}}) and the ionic radius of (Na+\mathrm{Na}^{+})is lesser than (1.86  A∘\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 :

Options

  1. ABoth Statement I and Statement II are false
  2. BStatement I is incorrect but Statement II is true
  3. CBoth Statement I and Statement II are true
  4. DStatement I is correct but Statement II is false

Correct answer

D. Statement I is correct but Statement II is false

Step-by-step solution

rNa>rNa+\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.
