- Source: List of molecules by year of discovery
Amedeo Avogadro created the word "molecule". His 1811 paper "Essay on Determining the Relative Masses of the Elementary Molecules of Bodies", he essentially states, i.e. according to Partington's A Short History of Chemistry, that:
The smallest particles of gases are not necessarily simple atoms, but are made up of a certain number of these atoms united by attraction to form a single molecule.
Millions of molecules have existed in the universe before the formation of Earth, elements have being mixed and formed molecules for millions of years, three of them, carbon dioxide, water and oxygen were necessary for the growth of life, even thought, we were able to see these substances we did not know what was their components.
The following is a table with a list of molecules organized by year of discovery of the components of these molecules.

=The sense developed among chemists that a number of substances were chemically related to benzene, comprising a diverse chemical family. In 1855, August Wilhelm von Hofmann used the word "aromatic" to designate this family relationship, after a characteristic property of many of its members.
August Kekulé was the principal formulator of the theory of chemical structure (1857–58). This theory proceeds from the idea of atomic valence, especially the tetravalence of carbon (which Kekulé announced late in 1857). His idea of assigning certain atoms to certain positions within the molecule, and schematically connecting them using what he called their "Verwandtschaftseinheiten" ("affinity units", now called "valences" or "bonds"),

=In 1903 Olinto De Pretto forumlated derived the energy–mass-equivalence E = m c 2 {\displaystyle E=mc^{2}} E=mc^{2}. This discovery was applied to Lambert's cosine law and Beer–Lambert laws to create Spectrophotometry technique that allowed to identify molecules and structures.
