Having a tendency to give away electrons and form positive ions in chemical reactions.
Sodium is an electropositive element that easily loses an electron to form a positive ion.
Electropositive is formed from "electro-" (from Greek "ēlektron", meaning amber or electricity) and "positive" (from Latin "positivus", meaning placed or affirmed). The term describes an element that has a tendency to lose electrons and thus has a positive charge.
Think of 'electricity' ('electro-') and 'affirmative' ('positive') to remember that 'electropositive' refers to elements that tend to lose electrons and carry a positive charge.
