- Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons 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.
- The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to caesium and francium which are the least electronegative
