Write an equation for: alpha a decay of radon - 198 beta b decay of uranium - 237 plutonium - 244 undergoes gamma decay !

Answer :

Alpha decay equation :

Beta decay equation :

Gamma decay equation :

Explanation :

Alpha decay : When a larger nuclei decays into smaller nuclei by releasing alpha particle. In this process, the mass number and atomic number is reduced by 4 and 2 units respectively.

       General representation of alpha decay :

       

Beta decay : In this process, a neutron is converted into a proton and an electron. In this decay, the atomic number is increased by 1 unit.

        General representation of beta decay :

       

Gamma decay : In this process, the unstable nuclei transformed into stable nuclei by releasing gamma rays. In this process, the mass number remains same.

        General representation of gamma decay :
