Question

what is electronegativity​

Answer 1

Answer:

Electronegativity, symbol χ, measures the tendency of an atom to attract a shared pair of electrons. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.

Answer 2

Answer:

The tendency of an atom in a molecule to attract the shared pair of electrons towards itself is known as electronegativity.

It is a dimensionless property because it is only a tendency. It basically indicates the net result of the tendencies of atoms in different elements to attract the bond-forming electron pairs. We measure electronegativity on several scales. The most commonly used scale was designed by Linus Pauling. According to this scale, fluorine is the most electronegative element with a value of 4.0 and cesium is the least electronegative element with a value of 0.7.
