The following are calculated values of valence shell orbital radii, Rmax. The properties of a solid can usually be predicted from the valence and bonding preferences of its constituent atoms. Cesium sulfide Strontium phosphide. In this case the covalent bonding seems to be preferred over the ionic bond. Ionic compounds are formed by a non-metal and metal. Describe how to name binary covalent compounds including acids and oxyacids. Substance B is brittle, does not conduct electricity as a solid but does when molten, and has a melting point of 2072 °C. In this glass, there are Si-O bonds, which are more covalent than ionic, and also Na-O and Ca-O bonds, which are more ionic than covalent. Further information is available in inorganic chemistry textbooks, usually at Level 1 or First Year University level. It can take three crystalline forms, but the hexagonal wurtzite structure shown is by far the most common.
