The incorrect decreasing order of atomic radii is

The incorrect decreasing order of atomic radii is
  1. $\mathrm{Si} \gt \mathrm{P} \gt \mathrm{Cl} \gt \mathrm{F}$
  2. $\mathrm{Be} \gt \mathrm{Mg} \gt \mathrm{Al} \gt \mathrm{Si}$
  3. $\mathrm{Al} \gt \mathrm{B} \gt \mathrm{N} \gt \mathrm{F}$
  4. $\mathrm{Mg} \gt \mathrm{Al} \gt \mathrm{C} \gt \mathrm{O}$

Solution

Correct order of atomic radii : $\mathrm{Be} < \mathrm{Mg}>\mathrm{Al}>\mathrm{Si}$
