Define divalent.

Explanation:
Divalent means having a valence of two. In chemistry, valence is the number of bonds an atom tends to form or the charge it typically carries in ionic form. When something is divalent, it can form two bonds or has a +2 or -2 charge. This is common for many metal ions in water treatment, like calcium and magnesium, which exist as Ca2+ and Mg2+. The sulfate ion also reflects divalence with a 2− charge. The idea isn’t about state of matter or a single charge; it’s about the ability to bond or balance with two partners.
