If carbon is not present, the elements are listed purely in alphabetical order of their symbol. This is the ‘Hill’ system used by Chemical Abstracts. This ordering is used in _chemical_formula_moiety and _chemical_formula_sum. _chemical_formula_项目指定化合物的组成和化学性质。分子式数据项...
The elements in a chemical formula are normally listed in a specific order, called the Hill system. In this system, the carbon atoms (if there are any) are usually listed first, any hydrogen atoms are listed next, and all other elements follow in alphabetical order. If the formula contains...
the molecular formula of the molecule, eg c7h6o2. the atomic symbols are in hill order: c is listed first, followed by h, followed by the remaining elements in alphabetical order. if the molecular formula is often used for searching, it is advised to create a database index on this ...

Chaucer’s gold would have been a mixture of elements, in a composition unknown and perhaps now unknowable. We can only describe the things for which we have words. Substances are hard to describe; transformations much harder. How can they be described? “If gold rust, what shall iron do?
