Amongst the elements with following electronic configurations, which one of them may have the highest ionization energy?
Ne [3s23p2]
Ar [3d104s24p3]
Ne [3s23p1]
Ne [3s23p3]
Ionization energy generally increases from left to right along the period while decreasing from top to bottom in a group.
Also, the half and fully filled are more stable electronic configurations.
Ne [3s23p3] and Ar [3d104s24p3] are more stable due to half filled p - orbitals but Ne [3s23p3] is smaller in size hence, more ionization energy.
