Electronegativity is increases in a group from top to bottom vertically because the atomic size of the elements is increases for higher atomic masses .

for example, 17th group elements, F - 4.0Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Cl - 3.0

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Br - 2.8

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â I - 2.5

Electronegativity is decreases in a period from left to right hoizontally because the atomic size of the elements is decreases for higher atomic masses.

for example 2nd period elements,Â Â

Li-1.0, Be-1.5, B-2.0, C-2.5, N-3.0, O-3.5, F-4.0.
