WebBeta decay is the loss of an electron from the nucleus of an atom. In Beta decay, a high-energy electron (called a beta particle) is emitted from a neutron in the nucleus of a radioactive atom. That neutron may be thought of as a combination of a beta particle (negative charge) with a proton (positive charge). The loss of the negatively charged … WebThe discovery of isotopes. Evidence for the existence of isotopes emerged from two independent lines of research, the first being the study of radioactivity. By 1910 it had become clear that certain processes associated with radioactivity, discovered some years before by French physicist Henri Becquerel, could transform one element into another ...
