30 Examples of Simple and Compound Substances

All substances they are formed by atoms, which in turn can form ionic compounds, molecules (organic and inorganic), crystalline structures and metallic compounds. The atom is the smallest unit that makes up matter and still retains the properties of the chemical element to which it belongs.

Molecules are stable, electrically neutral combinations of atoms. Great part of matter known is composed of molecules, which have enormous diversity in nature. Molecules can be simple or compound (also called chemical compounds).

Simple substances

The simple substances are those that are integrated only by a chemical element, which can appear in unitary form (a single atom) or in several atoms of the same chemical element. The important thing is that the molecules of the substance cannot be broken down or separated into their different constituent elements using physical separation methods.

Examples of simple substances

The following list shows simple molecules:

Compound substances

The compound substances are those that are formed by at least two atoms of two or more chemical elements, chemically united in defined proportions. This means that compound substances can be broken down into simple substances through certain reactions. which makes sense and is to be expected: elements are frequently in constant interaction between they.

Most substances are compound, and can be classified in two ways:

Depending on the number of elements in your formula, they can be:

Examples of compound substances

1. Ethyl alcohol or ethanol (CH₃CH₂OH or C₂H₆O, carbon, hydrogen and oxygen)
2. Sugar (Sucrose, C₁₂H₂₂OR₁₁, carbon, hydrogen and oxygen)
3. Acetone (CH₃Car₃ or C₃H₆O, carbon, hydrogen and oxygen)
4. Carbon dioxide (CO₂, carbon and oxygen)
5. Calcium sulfide (CaS, sulfur and calcium)
6. Sodium bicarbonate (NaHCO₃, sodium, carbon, hydrogen and oxygen)
7. Hydrochloric acid (HCl, hydrogen and chlorine)
8. Sulfuric acid (H₂SW₄, hydrogen, sulfur and oxygen)
9. Water (H₂Or, hydrogen and oxygen)
10. Chloroform (CHCl₃, carbon, chlorine and hydrogen)
11. Sodium oxide (Na₂O, oxygen and sodium)
12. Salt (NaCl, sodium and chlorine)
13. Ammonia (NH₃, nitrogen and hydrogen)
14. Carbon monoxide (CO, oxygen and carbon)
15. Potassium bromide (KBr, bromine and potassium)

There are usually three types of nomenclature to call both types of molecules (simple and compound):

Many times, compound molecules give rise to the generation of substances that have a specific name in themselves, thus opening a new nomenclature.
