Positron emission or beta plus decay (β+ decay) is a particular type of radioactive decay and a subtype of beta decay, in which a proton inside a radionuclide nucleus is converted into a neutron while releasing a positron and an electron neutrino (νe). Positron emission is mediated by the weak force. The positron is a type of beta particle (β+), the other beta particle being the electron (β−) emitted from the β− decay of a nucleus.
An example of positron emission (β+ decay) is shown with magnesium-23 decaying into sodium-23:
Because positron emission decreases proton number relative to neutron number, positron decay happens typically in large "proton-rich" radionuclides. Positron decay results in nuclear transmutation, changing an atom of a chemical element into an atom of an element with an atomic number that is less by one unit.
Positron emission should not be confused with electron emission or beta minus decay (β− decay), which occurs when a neutron turns into a proton and the nucleus emits an electron and an antineutrino.

This is also known as positron emission or beta plus decay, and it is another type of radioactive (nuclear) decay, along with alpha, beta, and electron capture. It affects the number of protons and neutrons in the nucleus, and causes a positron (a positively charged electron) to be released from the nucleus. Here, I give a review and introduction, and then do practice example problems.
This video tutorial focuses on subatomic particles found in the nucleus of atom such as alpha particles, beta particles, gamma rays, protons, electrons, positrons, and neutrons. It contains plenty of examples and practice problems.
