Question

why F posses highest electronegativity?

Answer 1

Answer:

Explanation:

Holla mate,

for group 17, effective nuclear charge is more than others,

so atomic radius is lowest, hence electronegativity is maximum.And since group 18 elements do not form covalent bonds,so electronegativity is not applicable for them...

Fluorine has the smallest atomic size in group 18 and hence has maximum electronegativity.

Answer 2

Flourine posses highest electronegativity because it is at left of the table,first in the halogens and mainly atomic weight decreases so,electronegativity increases.

Hope it helped you.
