To solve the problem step-by-step, we will analyze the decay processes of the uranium nucleus. ### Step 1: Identify the initial properties of the uranium nucleus. - The atomic number (Z) of uranium is 92. - The mass number (A) of uranium is 231. ### Step 2: Determine the effect of alpha decay. An alpha particle consists of 2 protons and 2 neutrons. When the uranium nucleus emits an alpha particle, the following changes occur: ...
