Radio activity is the process by which a nucleus of an unstable atom loses energy by emitting ionizing radiation. A material that spontaneously emits this kind of radiations which includes a, b, g rays is considered radioactive.The positively charged particle with 2 units of relative of charge and 4 units of mass isSelect an answerABCDpositron
