Answer: The beta decay reaction of Th-234 is written above.
Explanation:
Beta decay is defined as the decay process in which a neutron gets converted to a proton and an electron. In this decay process, beta particle is emitted. The emitted particle carries a charge of -1 units and has a mass of 0 units.
The released beta particle is also known as electron.
The chemical equation for beta decay process of Th-234 follows:
[tex]_{90}^{234}\textrm{Th}\rightarrow _{91}^{234}\textrm{Po}+_{-1}^0e^-+\gamma [/tex]
Hence, the beta decay reaction of Th-234 is written above.
