WebSep 16, 2024 · In chemistry and crystallography, the coordination number describes the number of neighbor atoms with respect to a central atom. The term was originally defined in 1893 by Swiss chemist Alfred Werner (1866–1919). The value of the coordination number is determined differently for crystals and molecules. The coordination number can … WebIn chemistry, non-stoichiometric compounds are chemical compounds, almost always solid inorganic compounds, having elemental composition whose proportions cannot be represented by a ratio of small natural numbers (i.e. an empirical formula ); most often, in such materials, some small percentage of atoms are missing or too many atoms are …
