Vedclass · Answer

(B) The ionisation enthalpy decreases down a group due to an increase in atomic size. Therefore,the ionisation enthalpy of $Ne$ is greater than that of $Ar$. Across a period,ionisation enthalpy generally increases with an increase in atomic number. Comparing the elements in the same period ($3^{rd}$ period),the order is $S Combining these trends,the correct decreasing order of ionisation enthalpy is: $Ne > Ar > Cl > S$.

Which of the following is the $CORRECT$ decreasing order of ionisation enthalpy for the given elements?
