S-1 : Formation of `Mg^(2+)` and `Al^(3+)` , both require the absorption of energy . S-2: The following set of elements represent the correct order of electron affinity values `S gt Se gt Te gt O` S-3 : The size of the isoelectronic species is affected by electron - electron interaction in the outer orbitals . S-4: Chemistry of the elements depend on the valence shell electron configuration as well as nuclear masses .
