Summary

The electron shell of the free atoms - this has already been pointed out earlier - can be stabilized not only by the union of identical atoms, but also of different types of atoms. If there are two types of atoms A and B, then they can combine with one another in different proportions: Am B.n. The type A connectionsmB.n (e.g. H.2O) are called binary connections. Their structure and their properties depend on those of components A and B, and in such cases it is not too difficult to infer the behavior of the compound from the properties of the atom. This becomes more difficult if the connection is made up of more than two types of atoms. The more complicated compounds can, however, be treated in the same way as the binary compounds if certain atomic groups can be differentiated in them as compound ions or radicals. Covalent forces act within the composite ions or radicals, so that in most cases there are separate and stable groups of atoms. The compounds that are built up from such groups of atoms can be viewed as binary compounds. A real binary connection is e.g. B. potassium chloride, but also potassium sulfate can be viewed as such on this basis.
