how many protons and electrons does aluminum ion have
In certain situations, however, the atom may lose or gain one or more electrons and acquire a net charge, becoming an ion. Aluminum, for instance, has an atomic number of 13, which tells us that an aluminum atom will have 13 protons. Given the fact that every proton has a positive charge, and that most atoms tend to be neutral in charge, this means that there are usually 13 electrons, with a negative charge, present in an atom of aluminum.
