Chemical elements

Elements and materials

An element is a substance made of one type of atom. Its atomic number is the number of protons in the atom’s nucleus, and the table is ordered by increasing atomic number. Different elements can combine chemically to form compounds, so an element named in a technology profile may be one part of a larger material.

These pages provide a bridge into Vrulum research rather than a complete chemistry reference. For fuller element data, see the Royal Society of Chemistry periodic table; for engineered materials, browse Vrulum materials profiles.
