Question

With respect to the Periodic Table, how does electronegativity evolve with respect to the individual elements?

Answer 1

`"Electronegativity increases across a Period.........."`

Explanation:

`"Electronegativity increases across a Period.........."`, from left to right as face the Table. And `"DECREASES"` down a Group, a column of the Periodic Table. See this old answer.

Given that you got `N,O,P,F`, clearly `F`, a `"Group 17 element"`, is the most electronegative element, followed by `"Group 16 oxygen"`, followed `"Group 15 nitrogen"`. And in last place of course is of course `"Group 15"` phosphorus, which comes from the next Period.

And so the order is `stackrel(F,O,N,P)"decreasing electronegativity"`.
