WebA proton is one of the subatomic particles that make up matter. In the universe, protons are abundant, making up about half of all visible matter.It has a positive electric charge (+1e) and a rest mass equal to 1.67262 × 10 −27 kg (938.272 MeV/c 2)— marginally lighter than that of the neutron but nearly 1836 times greater than that of the electron. WebWhen forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds.
