Of the following elements, which has the highest electronegativity ? A) Sc B) P C) S D) As
Got a Periodic Table...?
As we face the Table, electronegativity INCREASES across the Period from left to right as we face the Table. It decreases down the Group. And this is a consequence of nuclear charge, and the shielding offered by FULL electronic shells. Anyway, you should look up a Table of electronegativities.
