Chemical compound formulas refer to chemical substances that made up of many identical molecules that are composed of atoms from one or more than one element that are attached together by chemical bonds. Moreover, two atoms of the same element do not form chemical compounds as it requires two different elements.

**Types of Chemical Compounds**

Depending upon the constituents of atoms that held together, there are four types of compounds:

- Molecules
- Ionic Compounds
- Intermetallic compounds
- Complexes

**1. Molecules-** They are electrically neutral groups of two or more atoms that held together by a chemical bond. Furthermore, we can distinguish them from ions because they lack an electrical charge.

**2. Ionic Compounds-** These are chemical compounds that held together by the electrostatic charge that we call ionic bonding. Moreover, there are positively charged ions (cations) and negatively charged ions (anions).

**3. Intermetallic Compounds-** It is a type of metallic alloy that forms a solid-state compound that exhibits define stoichiometry and ordered crystal structure.

**4. Complexes-** These complexes or coordination complexes comprise of a central atom or ion that is typically metallic that we call the coordination center and a surrounding array of bound molecules or ions.
