The correct decreasing order of atomic radii ( pm ) of Li , Be , B and C is

Options

  1. ABe Li B C
  2. BLi Be B C
  3. CC B Be Li
  4. DLi C Be B

Correct answer

B. Li Be B C

Step-by-step solution

As the atomic number in a period increases, the effective nuclear charge also increases hence, atomic radii along the period decreases. Correct order of atomic radii Li Be B C
