WebA proton can be involved in a reaction that changes it into a neutron and vice versa, and there are several ways this can happen. A proton and electron can react with each other and form a neutron and an electron-neutrino. Or, a proton can emit a positron and an electron-neutrino and become a neutron. WebJun 11, 2009 · 662. 1. "antimatter" is kind of a bad name - it's still matter in most senses of the word. What makes it "anti" is that certain types of charges, like electric charge, are opposite for a particle and its antiparticle partner. The positron is just an electron with opposite electric charge - in all other ways they're identical.
