Dec 31, · The atomic number does indeed change. The atomic mass number does not. There are actually two kinds of beta decay; plus and minus. In beta minus decay an electron is produced as a down quark turns into an up quark, converting a neutron into a proton, resulting in a new element with an atomic number 1 greater than the decaying element but the same total number of baryons (protons . Positron emission or beta plus decay (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 (ν e). Positron emission is mediated by the weak force. Beta decay: Beta decay, any of three processes of radioactive disintegration by which some unstable atomic nuclei spontaneously dissipate excess energy and undergo a change of one unit of positive charge without any change in mass number. The three processes are electron emission, positron (positive electron).

The three processes are electron emission, positron (positive electron). Thus, ββ decay is usually studied only for beta stable nuclei. Like single beta decay, double beta decay does not change A; thus, at least one of the nuclides with some given A has to be stable with regard to both single and double beta decay. "Ordinary" double beta decay results in the emission of two electrons and two antineutrinos. Beta-minus decay occurs in nuclei with an excess of neutrons, while beta-plus decay takes place in neutron-deficit nuclei. A lot of natural background radiation on Earth is due to fission or alpha-decay of heavy radioactive elements. The remains of fission or alpha-decay are neutron-rich nuclei, so beta-minus decay is more common on Earth. Dec 31, · The atomic number does indeed change. The atomic mass number does not.

Positron emission is mediated by the weak force. Dec 30, · There are two types of beta decay, beta-minus, which I described in the previous paragraph, and beta-plus, in which a proton decays into a neutron, a positron, and a neutrino. Both reactions occur when an atom has either too many protons, or too many neutron in its nucleus.
