Vedclass · Answer

(B) Ionization potential is the amount of energy required to remove an outermost valence electron from an isolated gaseous atom.In a period,ionization potential generally increases from left to right due to an increase in effective nuclear charge.$Ne$ is a noble gas with a completely filled octet,giving it the highest ionization potential among the given elements.Comparing $P$ $(3s^2 3p^3)$ and $S$ $(3s^2 3p^4)$: $P$ has a stable half-filled $p$-orbital,making its ionization potential higher than $S$.Comparing $Mg$ $(3s^2)$ and $Al$ $(3s^2 3p^1)$: $Mg$ has a stable fully-filled $s$-orbital,making its ionization potential higher than $Al$.Thus,the correct decreasing order is: $Ne > Cl > P > S > Mg > Al$.
