The decreasing order of the ionization potential of the following elements is:
The decreasing order of the ionization potential of the following elements is:
Show Hint
Half-filled and fully filled orbitals have extra stability.
Updated On: Mar 20, 2026
- Ne > Cl > P > S > Al > Mg
- Ne > Cl > P > S > Mg > Al
- Ne > Cl > S > P > Mg > Al
- Ne > Cl > S > P > Al > Mg
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Ionization energy increases across a period and decreases down a group.
Step 2: Noble gases have the highest ionization energy.
Step 3: Due to half-filled stability, P > S.
