This page decribes the structures of giant covalent substances like diamond, graphite and silicon dioxide (silicon(IV) oxide), and relates those structures to the physical properties of the substances. In diamond, each carbon shares electrons with four other carbon atoms - forming
Simple molecular structures consist of atoms or molecules bound by intermolecular forces arising from hydrogen bonding and dipole-dipole interactions. Giant structures are formed are atomic networks strong bonded to each other. The most common types of giant structures are metals, ionic solids, polymers, ceramics and

Polymers are very long molecules and the main component in many common plastic materials. On this page the molecular structure and uses of the polymers poly(ethene), poly(propene), poly(chloroethene)/PVC and polystyrene are described. Problems with waste plastics and recycling of plastics is also discussed.
Thermosetting plastics are quite different. In the production of thermosetting plastics, covalent bonds are made between the original polymer chains to give a cross-linked structure which is essentially one huge molecule. Because covalent bonds have to be broken to allow anything to move, much more heat has to be
Polymers are macro-sized molecules of relatively high molecular mass, which find extensive use in our daily life. Polymers are large but single chain-like molecules in which the repeating unit derived from small molecules called monomers are covalently linked. Structurally, they are characterized by many repeating
In the solid, the BeCl2 molecules polymerise to make long chains. They do this by forming coordinate bonds (dative covalent bonds) between lone pairs on chlorine atoms and adjacent beryllium atoms. The diagram shows a simple dimer - the start of the polymerisation process.
EL(j) the bonding in giant lattice (metallic, ionic, covalent network) and simple molecular structure types; the typical physical properties DF(c) the relation of molecular shape to structural formulae and the use of wedges and dotted lines to represent 3-D shape. OZ(a) the term . polymer 'slime' which is always very popular.
The physical properties of molecular substances. Molecules are made of fixed numbers of atoms joined together by covalent bonds, and can range from the very small (even down to single atoms, as in the noble gases) to the very large (as in polymers, proteins or even DNA). The covalent bonds holding the molecules
COVALENT BONDING - DOUBLE BONDS. This page explains how double covalent bonds arise. It starts with a simple picture of double covalent bonding, and then takes a more sophisticated view of the bonding in ethene.
