1. Having a negative electric charge B2 formal scientific

   Describes an object, particle, or region that carries an excess of electrons, resulting in a negative electric charge.

   • The electronegative terminal of the battery is usually marked with a minus sign.
   • In electrolysis, ions move toward the oppositely charged electrode; negative ions (anions) are electronegative.
   • The electron cloud in a molecule may become electronegative near certain atoms.
