Question

Which of the following is CORRECT for the atomic and ionic radii of alkali metals?

विकल्प

• Li⁺ is larger than Li

• Li is smaller than Na

• Na is smaller than Na⁺

• K is smaller than Na

Answer 1

Li is smaller than Na

Explanation:

The atomic radii of parent atoms are less than the ionic radii of alkali metals. As you move down the group, the atomic and ionic radii rise.
