Why is electronegativity not measurable?
Why is electronegativity not measurable? Answer. 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. Why electronegativity is a dimensionless property? The tendency of […]
