An element composed of molecules consisting of two atoms of that element is called a diatomic element.

Here are some examples of diatomic elements:

* Hydrogen (H₂)

* Nitrogen (N₂)

* Oxygen (O₂)

* Fluorine (F₂)

* Chlorine (Cl₂)

* Bromine (Br₂)

* Iodine (I₂)

These elements exist naturally as pairs of atoms bonded together. This is because they are more stable in this form than as individual atoms.
