In this question we are assigned with the task to find the major product that is formed as a result of beta decay by thorium 232 isotope.
00:22
Mass number of thorium is 232 and atomic number of thorium is 90.

Before getting into the question, let us understand what is beta decay of a radioactive isotope.
00:38
Any radioactive isotope, for example, a radioactive element x with a mass number m and atomic number a undergoing a beta emission will result in producing a beta particle.
00:55
Beta particle is nothing but a particle which has a mass number of zero and with a charge of minus 1.
01:04
Eventually, the daughter nucleus that is formed as a result of beta decay, let us mention the daughter nucleus as y, will have the mass number unchanged, hence the mass number will be m as thought of its parent nucleus, and its atomic number will be increased by 1, hence it will be a plus 1...
