Hydration causes water molecules to coordinate around the ions. But how do we know how many form the hydration shell? It certainly has something to do with the charge and the ion size, but can this possibly be predicted?
As a rule, non-alloy metals which, in some cases, react chemically vigorously and combine with other substances. These are, for example, sodium in the sodium chloride (sodium chloride), potassium (ali salts), calcium (salts of carbonic acid) in rocks (alkstone). In general, many rocks are salts or oxides of base metals and non-metals such as halogens, acid residues or even oxygen.
The alkali metals, the alkaline earth metals. Unedle metals do not appear in pure form in nature. They’re too reactive. Sodium, potassium, lithium, beryllium, calcium, strontium, barium…
