Root Explanation

Trivalent → It is formed from "tri-" (meaning three) and "valent" (from Latin "valens", meaning having strength or capacity). The word "trivalent" refers to having a valence of three, indicating the ability to bond with three other atoms or groups.

Memory Tip

Think of 'tri-' meaning three, and 'valent' relating to strength or capacity — so trivalent means having the capacity to bond with three.
