Explanation:
If a uranium atom undergoes both alpha and gamma decay, then it means that there will be formation of one helium particle which is also known as alpha particle and gamma decay is the radiation or release of energy.
Whereas in a radioactive reaction, Uranium-235 absorbs a neutron and splits into two new atoms. As a result, there is formation of 3 new neutrons and a large amount of binding energy.
This reaction is as follows.
Thus, we can conclude that if a uranium atom undergoes both alpha and gamma decay, then the following will happen.
The nucleus loses neutrons.The nucleus loses energy.
