Electronegativity - Wikipedia

Electronegativity, symbol , 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. The higher the associated electronegativity number, the more an atom or a substituent group attracts Copper Facts: Chemical and Physical PropertiesCopper is atomic number 29 with element symbol Cu.
