allotrope - Computer Definition
A chemical element that can take on different forms based on the structure of, or the number of atoms in, the molecule. The most common example is carbon. If carbon atoms are bonded in a lattice of four triangular surfaces (tetrahedral), it is a diamond. If the atoms are bonded in sheets of six-sided (hexagonal) lattice, it is graphite. See isotope.
