This is an index of lists of molecules (i.e. by year, number of atoms, etc.). Millions of molecules have existed in the universe since before the formation of Earth. Three of them, carbon dioxide, water and oxygen were necessary for the growth of life.

Molecules with three atoms, the same or varying. Subcategories. This category has only the following subcategory. H. ... Carbon dioxide; Cyanogen bromide; Cyanogen ...
Compounds containing oxygen in other oxidation states are very uncommon: − 1 ⁄ 2 (superoxides), − 1 ⁄ 3 , 0 (elemental, hypofluorous acid), + 1 ⁄ 2 , +1 (dioxygen difluoride), and +2 (oxygen difluoride). Oxygen is reactive and will form oxides with all other elements except the noble gases helium, neon, argon and krypton. [1]
Ozone, O 3 is an example of a triatomic molecule with all atoms the same. Triatomic hydrogen, H 3, is unstable and breaks up spontaneously. H 3 +, the trihydrogen cation is stable by itself and is symmetric. 4 He 3, the helium trimer is only weakly bound by van der Waals force and is in an Efimov state. [1] Trisulfur (S 3) is analogous to ozone.
Three-carbon molecules are based on a skeleton made from three carbon atoms. They may be in a chain, or cycles. C3 hydrocarbons are usually gases, they are inflammable, and may be harmful to humans and the environment. [1] The CAS registry number for three-carbon hydrocarbons is 68606-26-8. Hydrocarbons that include three atoms are: Propane C 3 ...
The most known chemical elements whose covalent combinations make up most biological molecules on Earth. [2] All of these elements are nonmetals.. In animals in general, the four elements—C, H, N, and O—compose about 96% of the weight, and major minerals (macrominerals) and minor minerals (also called trace elements) compose the remainder.
Normally, carbon is tetravalent, while oxygen is divalent, and in most oxocarbons (as in most other carbon compounds) each carbon atom may be bound to four other atoms, while oxygen may be bound to at most two. Moreover, while carbon can connect to other carbons to form arbitrarily large chains or networks, chains of three or more oxygens are ...
