Answer 2

Electronegativity : The tendency of the elements to gain electrons and form negative ions. The elements are generally non-metals.

Electronegativity increases up the group and increases across the period too. (General-Trend)

Neon is a noble gas, so it will neither lose any electron nor give any electron as it is already stable and having it's octet complete!

So, the order is : Ne < Al < S < O
