The correct order of atomic radii of given elements is

Options

  1. AB Be Mg
  2. BMg Be B
  3. CBe B Mg
  4. DB Mg Be

Correct answer

A. B Be Mg

Step-by-step solution

In periodic table atomic radii decrease from left to right and increase from top to bottom. Mg is placed in 3 rd period and Be , B are in second period so, Mg have more atomic radii then Be and B .
