Answer 1

Answer:

Hello friend..

Here's your answer : This is because as you go from left to right across a period, the nuclear charge is increasing faster than the electron shielding, so the attraction that the atoms have for the valence electrons increases. The electronegativity of atoms decreases as you move from top to bottom down a group in the periodic table.
