Ions with names ending in "-ide" are typically monatomic anions, meaning they are negatively charged ions formed from a single atom.

Here are some examples:

* Chloride (Cl⁻)

* Fluoride (F⁻)

* Bromide (Br⁻)

* Iodide (I⁻)

* Oxide (O²⁻)

* Sulfide (S²⁻)

* Nitride (N³⁻)

* Phosphide (P³⁻)

There are a few exceptions to this rule, such as:

* Cyanide (CN⁻) - This is a polyatomic anion (containing multiple atoms)

* Hydroxide (OH⁻) - This is also a polyatomic anion

However, in general, if you see an ion name ending in "-ide", it's safe to assume it's a monatomic anion.
