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.
Chemical substance – Form of matter; Inorganic compounds by element; List of alloys; List of alkanes; List of elements by name; List of minerals – List of minerals with Wikipedia articles; List of alchemical substances; Polyatomic ion – Ion containing two or more atoms; Exotic molecules – Atoms composed of exotic particles can form ...
Chemical structures are presented to help readers understand the nature of the titled material. One can subdivide chemical compounds into two main groups: molecules, which includes most organic, polyatomic gases, and organometallic compounds, and nonmolecular species, which includes most purely inorganic compounds. The structures of many ...
A list of chemical analysis methods with acronyms. A. Atomic absorption spectroscopy (AAS) Atomic emission spectroscopy (AES) Atomic fluorescence spectroscopy (AFS) ...
Progress on the articles in this list is monitored by participants. Also, templates for Lists of Properties for the compounds have been standardized, as has formatting and naming articles on chemical compounds. Presentation of chemical structures should also be standardized (to some extent). This WikiProject also serves as a forum on how best ...
Structural chemistry is a part of chemistry and deals with spatial structures of molecules (in the gaseous, liquid or solid state) and solids (with extended structures that cannot be subdivided into molecules). For structure elucidation [1] a range of different methods is used.
(only simple oxides, oxyhalides, and related compounds, not hydroxides, carbonates, acids, or other compounds listed elsewhere) P. Pd Palladium ...
Theories of chemical structure were first developed by August Kekulé, Archibald Scott Couper, and Aleksandr Butlerov, among others, from about 1858. [4] These theories were first to state that chemical compounds are not a random cluster of atoms and functional groups, but rather had a definite order defined by the valency of the atoms composing the molecule, giving the molecules a three ...
