A simple chemical is defined by opposition to the macromolecule, as a chemical compound that is not formed by the covalent linking of pseudo-identical residues. Examples of simple chemicals are: an atom, a monoatomic ion, a salt, a radical, a solid metal, a crystal etc.

Specification

container:

A simple chemical is represented by a circular container.

label:

The identification of the simple chemical is carried by an unbordered box containing a string of characters. The characters may be distributed on several lines to improve readability, although this is not mandatory. The label box has to be attached to the center of the container box. Note that the label can spill-over from the container box.

auxiliary items:

A simple chemical can carry one or several units of information. A particular unit of information carries the physical type of the simple chemical.
