A chemical compound is a molecular substance consisting of multiple atoms which are bonded together by a chemical reaction. This type can be used for compounds made of the same element (e.g. allotropes) or multiple different elements. Compounds are different from chemical mixtures because mixtures can be mixed and separated physically, without a reaction.

• Compounds that only contain one element (e.g.: Dioxygen)

• Compounds that are used for medical treatments (e.g.: Aspirin)

• Compounds that are drugs (e.g.: Cocaine)

• Compounds that are hormones (e.g.: Seratonin)

• Vitamins (e.g.: Riboflavin aka Vitamin B2)

• Polymers (e.g.: Polyglycolide, Amylose)

• Individual elements (e.g.: Neon)

• Use the chemical element type

• Chemical mixtures and alloys (e.g.: Bitumen, Smoke, and Brass)

• Isotopes (e.g.: Hydrogen 1, Plutonium 241)

• Use the Isotope type

• Formulas and equations (e.g.: Chemical formula, Empirical formula, Structural formula)

• There is no type necessary for formulas and equations

• Chemical Classifications (e.g.: Glycoprotein, Acid)

• Use the Chemical Classification type
