3.6: Names and Formulas of Inorganic Compounds

The atoms in all substances that contain multiple atoms are held together by electrostatic interactions—interactions between electrically charged particles such as protons and electrons. Electrostatic attraction between oppositely charged species positive and negative results in a force that causes them to move toward each other, like the attraction between opposite poles of two magnets. In contrast, electrostatic repulsion between two species with the same charge either both positive or both negative results in a force that causes them to repel each other, as do the same poles of two magnets. Atoms form chemical compounds when the attractive electrostatic interactions between them are stronger than the repulsive interactions. Collectively, the attractive interactions between atoms are called chemical bonds. Chemical bonds are generally divided into two fundamentally different types: ionic and covalent. In reality, however, the bonds in most substances are neither purely ionic nor purely covalent, but lie on a spectrum between these extremes.

In the GCSE exams, chemical formulae are often given to you in the question. Remember our top three tips for each type of compound… and writing chemical formulae will never be a problem again! First off, decide if the compound is covalent or ionic. Remember that covalent bonding happens when all the elements in a molecule are non-metals e. The name starts with the atom at the centre of the molecule, and then tells you how many of the other elements there are. For example:.
