NEET Chemistry Atomic Radius Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Cation | (i) Larger than parent atom |
| (b) Anion | (ii) Smaller than parent atom |
| (c) Atomic radius | (iii) Measured by bond distance |
| (d) Ionic radius | (iv) Same trend as atomic radius |
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-iv, c-iii, d-i
a-iv, b-iii, c-i, d-ii
Correct Answer
Detailed Explanation
A cation is smaller than its parent atom due to the loss of electrons, while an anion is larger because the gain of electrons increases electron-electron repulsion. The ionic radius trend follows that of atomic radius, as noted in the NCERT context.
