Which of the following series correctly represents relations between the elements from $X$ to $Y ?$ $\mathrm{X} ightarrow \mathrm{Y}$
  1. ${ }_{3} \mathrm{Li} ightarrow{ }_{19} \mathrm{~K}$ Ionization enthalpy increases
  2. ${ }_{9} \mathrm{~F} ightarrow{ }_{35} \mathrm{Br}$ Electron gain enthalpy (negative sign) increases
  3. ${ }_{6} \mathrm{C} ightarrow{ }_{32}$ Ge Atomic radii increases
  4. $18 \mathrm{Ar} ightarrow{ }_{54} \mathrm{Xe}$ Noble character increases

Solution

On moving down a group atomic radii increases.
