Why are ionic compounds so easy to name? 6) GaCl3 gallium chloride. 13) methane CH4 Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula SiO 2, most commonly found in nature as quartz and in various living organisms. Because the difference in electronegativity between sulfur (S) and oxygen (O) is low enough to result in sharing of electrons which leads to the formation of a covalent bond in SO2. Let's Practice CO2 N2O4 P4O10 CO Example: . Answer (1 of 16): First of all we know that {Metal- Metal} & {Non-metal - Non-metal} forms Covalent bonds and {Metal - Non-Metal} forms ionic bonds (Basic says). If the compound is binary, ends in -ide. Since, the loss of electrons by one and gain by . The nomenclature of binary covalent compounds follows these rules: These examples show how the rules are applied for the covalent compounds formed by nitrogen and oxygen: To avoid awkward . On the other hand F- has a small size due to which it is tuff to polaris it, but Cl-, having a large size, is easily polarisible. Thus covalent compounds are the basis of life on earth. Naming Molecular Compounds All the molecular compounds you'll be asked to name are binary. This is a giant covalent structure - it continues on and on in three dimensions.
