Divalent

Alright kiddo, let me help you understand what divalent means. So, you know how some things are made up of many tiny pieces called atoms? And each atom has even tinier pieces inside it called electrons?

Well, sometimes atoms share their electrons with other atoms to make bonds and form a molecule. And when an atom shares two of its electrons with another atom, we call it a divalent molecule.

It's kind of like you and your friend each have a toy car, but you decide to share one of your cars with them so both of you have two. In the same way, atoms can share their electrons with other atoms to create a stronger bond and form a divalent molecule.

Examples of divalent molecules are things like calcium (Ca2+), which has two electrons that it shares with other atoms. This makes it important for building strong bones and teeth.

So, in summary, divalent means a molecule that is made up of two electrons shared between two atoms.
