Question

electronegativity is a dimensionless property, how?

Answer 1

because no unit is use in this

Answer 2

A qualitative measure of the ability of an atom in a chemical compound to attract shared electrons to itself is called Electronegativity (E.N.). It is not a measurable quantity. It is a dimensionless property because it is only a tendency. It generally  indicates the net result of the tendencies of atoms in different elements to attract the bond forming electron pairs.
