WebThe given diagram of decay of bismuth-212 is as follows: From the given diagram it is clear that decay of bismuth-212 gives alpha particle and A. Alpha particle releases means the decay is alpha decay. In alpha decay, mass number decrease by 4 and atomic number decreases by 2. So, the nuclear equation is, B 83 212 i → H 2 4 e + T 81 208 i A Webbeta 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) emission, and electron capture.
