Which from following is a CORRECT decreasing order of ionization enthalpies of different elements?

Which from following is a CORRECT decreasing order of ionization enthalpies of different elements?
  1. $\mathrm{S}>\mathrm{Se}>\mathrm{Te}>\mathrm{Po}$
  2. $\mathrm{Te}>\mathrm{Po}>\mathrm{S}>\mathrm{Se}$
  3. $\mathrm{S}>\mathrm{Te}>\mathrm{Po}>\mathrm{Se}$
  4. $\mathrm{Te}>\mathrm{Po}>\mathrm{Se}>\mathrm{S}$

Solution

The ionization enthalpy decreases down the group due to increase in the atomic size. The correct decreasing order of ionization enthalpies is: $\mathrm{S}>\mathrm{Se}>\mathrm{Te}>\mathrm{Po}$
