Study of the Properties of Group B Metals in the Laboratory

The formation of ionic bonds is possible only between atoms whose electronegativity differs by a very significant amount. There are relatively few ionic compounds. It is worth remembering that these include halides and oxides of alkali (the main subgroup of the first group) and alkaline earth (the main subgroup of the second group) metals. Ions can also consist of several atoms. Within such ions, the bonds are not ionic (they will be discussed below), but between ions they are ioni
