How do you explain the variation of atomic radius in a period and group?

Options

  1. AAtomic radius decreases from left to right in a period due to increased nuclear charge and increases from top
  2. BAtomic radius increases from left to right in a period due to increased nuclear charge and increases from top
  3. CAtomic radius decreases from left to right in a period due to decreased electron-electron repulsion and increa
  4. DAtomic radius increases from left to right in a period due to increased electron-electron repulsion and decrea

Correct answer

A. Atomic radius decreases from left to right in a period due to increased nuclear charge and increases from top

Step-by-step solution

Correct Option is : (A) Atomic radius decreases from left to right in a period due to increased nuclear charge and increases from top to bottom in a group due to the addition of energy levels.
