The elements of group I are called the alkali metals. They each have one s electron in the outer shell and we shall see that there are very strong family resemblances between them. The elements of group II are called the alkaline earth metals. They have two s electrons in the outer shell and they too show obvious family resemblances. We thus fmd that the chemistry of the elements in these two groups can be briefly summarised by a number of simple generalisations.
