Question

explain variation of electronegativity in periodic table

Answer 1

Answer:

ln a period Electronegativity increases on moving left to right.In a group Electronegativity decreases on moving down the group.

Electronegativity depends on

1) Atomic radius

2)Nuclear charge

Greater the nuclear charge greater is the electronegativity

Smaller the atomic radius greater is the Electronegativity.

Explanation:

HIGHEST ELECTRONEGATIVITY > Fluorine. LOWEST ELECTRONEGATIVITY < Cesium
