The proton is positively charged, and the neutron has no charge. The electron is negatively charged.(3.1d) Protons and electrons have equal but opposite charges. The number of protons equals the number of electrons in an atom. (3.1e) The mass of each proton and each neutron is approximately equal to one atomic mass unit.

Proton (+) Neutron (neutral) 1 amu = 1.6606 x 10-24 g. A is the mass number . Z is the atomic number The nucleus of an atom contains the protons and the neutrons. 1H and 2H are isotopes of hydrogen. 12C and 13C are isotopes of carbon. An ion is a charged particle, O2- and Na+ are ions.

Protons and neutrons both have a mass of 1 amu. The mass of the electron is negligible compared to the mass of the proton and neutron. Thus the mass number, or the mass of the atom, is the sum of the number of protons and neutrons.

results in the emission of a high speed positron and, in the nucleus, a proton is converted into a neutron. 4) Electron capture. occurs when an electron from the electron cloud gets pulled into the nucleus and converts a proton into a neutron. (Notice that there are. two . ways to convert a proton into a neutron.) 5) Gamma radiation (
