In the context of zeolites, the term heteroatom refers to partial isomorphous substitution of the typical framework atoms (silicon, aluminium, and phosphorus) by other elements such as beryllium, vanadium, and chromium. The goal is usually to adjust properties of the material (e.g., Lewis acidity) to optimize … See more In chemistry, a heteroatom (from Ancient Greek heteros 'different', and atomos 'uncut') is, strictly, any atom that is not carbon or hydrogen. See more It can also be used with highly specific meanings in specialised contexts. In the description of protein structure, in particular in the Protein Data Bank file format, a heteroatom record (HETATM) describes an atom as belonging to a small molecule cofactor rather than … See more In practice, the term is usually used more specifically to indicate that non-carbon atoms have replaced carbon in the backbone of the molecular structure. Typical heteroatoms are nitrogen (N), oxygen (O), sulfur (S), phosphorus (P), chlorine See more • Journal - Heteroatom Chemistry See more WebJul 12, 2024 · Heteroatomic molecules are molecules that do not have the same atoms making up the molecule. Lithium is a different atom than fluoride, and lithium fluoride is a molecule. Therefore, it is a heteroatomic molecule. What is meant by Homoatomic? Filters.
