The Aluminum Atom Gains. Aluminum, for instance, has an atomic number of 13, which. The mg 2 + ion, the al 3 + ion, the na + ion, and the elemental n e atom are all isoelectronic. atoms of group 17 gain one electron and form anions with a 1− charge; when an atom gains an electron it gains a negative charge and is called an anion. to find the electron configuration of an atom, you first need to know the number of electrons that it has. some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet. in the particular example of aluminum, aluminum had an initial charge of zero, thanks to the 13 electrons and 13 protons canceling one out. The reasons for gaining and losing electrons. Atoms of group 16 gain two electrons and form ions with a 2−. the aluminum atom loses its three valence electrons. For most elements under typical conditions, three electrons is the maximum number that will be lost or gained. in certain situations, however, the atom may lose or gain one or more electrons and acquire a net charge, becoming an ion. when forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet.
