Q9 / 90 · JEE Main 2024 (05 Apr Shift 2) · Chemistry
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 :
- ABoth Statement I and Statement II are false
- BStatement I is incorrect but Statement II is true
- CBoth Statement I and Statement II are true
- Correct answerDStatement 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.
So, Statement (I) is correct but size of anions are greater than size of neutral atoms. So statement (II) is incorrect.
Hence, the correct answer is option: 'D'.
