In other words, if all electrons are removed, the role of daughter and mother in the decay is inverted, and ²⁰⁵Tl undergoes a beta minus decay to ²⁰⁵Pb. This is what happens in AGB stars ...

In the most common form of this decay, beta-minus decay, a neutron decays into a proton, also spitting out a negatively charged electron in order to conserve electric charge; beta-plus decay does ...

Beta (\(\beta^-\)) decay is the release of an electron by the change of a neutron to a proton. The neutron (charge = 0) is made up of one up quark (charge = \(\frac{2}{3}\)) and two down quarks ...
