Q.
Given below are two statements:

Statement I: The metallic radius of Na is 1.86 A° and the ionic radius of ${Na}^{+}$ is lesser than 1.86 A°.

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 : [2024]

1 Statement I is correct but Statement II is false

2 Both Statement I and Statement II are false

3 Both Statement I and Statement II are true

4 Statement I is incorrect but Statement II is true

Ans.
(1)

Cations are formed by losing electrons hence are smaller than parent atom. Anions are formed by gaining electrons hence are larger than parent atom.

Solution

1 Statement I is correct but Statement II is false

2 Both Statement I and Statement II are false

3 Both Statement I and Statement II are true

4 Statement I is incorrect but Statement II is true

Ans.
(1)
