Elements in the periodic table that have similar chemical and physical properties belong to the same family. This is because elements of the same family have the same number of electrons in the last electron shell.
Elements of the same family in the periodic table
Examples of the above situation are:
Lithium, sodium, pótassium, rubidium, cesium and francium. These are elements that are located in family 1A of the table, and that have a single valence electron. Furthermore, for its position in the table to be discovered, it is sufficient to perform the electronic distribution of the atom in its ground state.
