Self-healing rubber is an example of a molecular solid with the potential for significant commercial applications. The compound tetraphosphorus pentasulfide is a covalent compound as the molecule is formed by covalent bonds, in which the atoms share one pair or more than one pair of valence electrons. The categories are distinguished by the nature of the interactions holding the discrete molecules or atoms together. Because of their malleability (the ability to deform under pressure or hammering), they do not shatter and, therefore, make useful construction materials. Borax is a mineral that is taken straight from the ground (a form of the element Boron) and used in cleaning products. Greek prefixes are not used for binary ionic compounds.
