Other metal examples include austenite and ferrite, but they are more common among non-metals due to varied crystalline structures. One subset of these reverts to the P4 form upon melting and is classified as red or white, while many are given the prefix di-. The ones classified as S8 are named by Greek letters, and other sulfur examples have different numbers of atoms in their rings. Carbon's examples include fullerene, graphite, and diamond.  Identify these variants of elements based on molecular structure sometimes contrasted with isotopes.
