JEE Mains · Chemistry · STD 11 - 3. Classification of elements and periodicity in properties
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 :
- A Statement \(I\) is correct but Statement \(II\) is false
- B Both Statement \(I\) and Statement \(II\) are true
- C Both Statement \(I\) and Statement \(II\) are false
- D Statement \(I\) is incorrect but Statement \(II\) is true
Answer & Solution
Correct Answer
(A) Statement \(I\) is correct but Statement \(II\) is false
Step-by-step Solution
Detailed explanation
\(\mathrm{r}_{\mathrm{Na}}>\mathrm{r}_{\mathrm{Na}^{+}}\) So, Statement \((I)\) is correct but size of anions are greater than size of neutral atoms. So, statement \((II)\) is incorrect.
