Is electronegativity the tendency to attract electrons?

Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons (or electron density) towards itself. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.

Explanation:

Yes

Explanation:

The higher the electronegativity the higher tendency to attract electrons, the lower the electronegativity the higher tendency to give away electrons/lose electrons.
