S2.2 The covalent model (3)
This is the third part of S2.2 The covalent model. It covers the structure and properties of silicon, silicon dioxide and the allotropes of carbon. It also covers the factors that affect the strength of the intermolecular forces of attraction between covalent compounds and the properties such as volatility, electrical conductivity and solubility that are influenced by them. What determines the covalent nature and...
