[e-lek″tro-neg´ah-tiv]

bearing a negative electric charge.

e·lec·tro·neg·a·tive

(ē-lek'trō-neg'ă-tiv),

1. Relating to or charged with negative electricity.

2. Referring to an element whose uncharged atoms have a tendency to ionize by adding electrons, thus becoming anions (for example, oxygen, fluorine, chlorine).
