The correct order of atomic radii of N, F, Al, Si is

The correct order of atomic radii of N, F, Al, Si is
  1. $\mathrm{F}\gt\mathrm{N}\gt\mathrm{Si}\gt\mathrm{Al}$
  2. $\mathrm{F}\gt\mathrm{N}\gt\mathrm{Al}\gt\mathrm{Si}$
  3. $\mathrm{Al}\gt\mathrm{Si}\gt\mathrm{F}\gt\mathrm{N}$
  4. $\mathrm{Al}\gt\mathrm{Si}\gt\mathrm{N}\gt\mathrm{F}$

Solution

In periodic table, left to right atomic radii decreases and from top to bottom atomic radii increases. $\therefore \quad \mathrm{Al}\gt\mathrm{Si}\gt\mathrm{N}\gt\mathrm{F}$
