Question

Given below are two statements:

Statement I: The metallic radius of Na is 1.86  and the ionic radius of Na+ is lesser than 1.86  .

Statement II: Ions are always smaller in size than the corresponding elements.

Strategy:
 Compare elements to their ions. Cations are formed by losing electrons (leading to a decrease in size), while anions are formed by gaining electrons (leading to an increase in size).

Step 1: Evaluate Statement I
- Sodium () loses an electron to form .
-  has one fewer shell and higher , making it smaller (). (True)

Step 2: Evaluate Statement II
- Ions include both cations (smaller) and anions (larger).
- Anions (e.g., ) are larger than their parent atoms.
- Therefore, the statement
