What is formed of two atoms?

Answer 1

There are several types of diatomic molecules, that is molecules formed by two atoms.

Molecules formed by two identical atoms are frequent like gaseous hydrogen and oxygen (H2 and O2) while other molecules are made by different atoms like carbon monoxide (CO), nitric oxide (NO), and hydrogen chloride (HCl).

It is to be noted that diatomic molecules have to be distinct by substances that are not formed by separated molecules, but where two atoms are present in an equal stoichiometric ratio. For example, solid NaCl (that is common cooking salt) is a crystal with a number of sodium atoms equal to the number of chloride atoms. In a crystal a regular disposition of atoms of different kinds is present where individual molecules cannot be insulated.

Answer 2

A molecule forms from two or more atoms such as oxygen gas (O2). A compound forms with two or more different atoms such as in water (H2O)
