The two types of beta decay are known as beta minus and beta plus.In beta minus (β −) decay, a neutron is converted to a proton, and the process creates an electron and an electron antineutrino; while in beta plus (β +) decay, a proton is converted to a neutron and the process creates a positron and an electron neutrino. β + decay is also known as positron emission.
Positron emission, beta plus decay, or β+ decay is a subtype of radioactive decay called beta decay, in which a proton inside a radionuclide nucleus is converted into a neutron while releasing a positron and an electron neutrino ( νe ). [ 1] Positron emission is mediated by the weak force.
Redox ( / ˈrɛdɒks / RED-oks, / ˈriːdɒks / REE-doks, reduction–oxidation [2] or oxidation–reduction [3] : 150 ) is a type of chemical reaction in which the oxidation states of the reactants change. [4] Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the ...
A beta particle, also called beta ray or beta radiation (symbol β ), is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay. There are two forms of beta decay, β − decay and β + decay, which produce electrons and positrons respectively. [ 2]
John 3:16. John 3:16 is the sixteenth verse in the third chapter of the Gospel of John, one of the four gospels in the New Testament. It is deemed one of the most popular verses from the Bible and is a summary of one of Christianity's central doctrines; the relationship between the Father (God) and the Son of God (Jesus).

The four most common modes of radioactive decay are: alpha decay, beta decay, inverse beta decay (considered as both positron emission and electron capture), and isomeric transition. Of these decay processes, only alpha decay (fission of a helium-4 nucleus) changes the atomic mass number ( A ) of the nucleus, and always decreases it by four.
Naturally occurring cerium(58Ce) is composed of 4 stable isotopes: 136Ce, 138Ce, 140Ce, and 142Ce, with 140Ce being the most abundant (88.48% natural abundance) and the only one theoretically stable; 136Ce, 138Ce, and 142Ce are predicted to undergo double beta decaybut this process has never been observed. There are 35 radioisotopesthat have ...
