What is the beta decay equation for $^{81}\mathrm{Tl}_{205}$?

Answer:

Beta decay ($\beta$ decay) is a type of radioactive decay in which a proton is transformed into a neutron, or vice versa, inside an atomic nucleus. This process allows the atom to move closer to the optimal ratio of protons and neutrons. As a result of this transformation, the nucleus emits a detectable beta particle, which is an electron or positron.

In fully ionized state, the isotope $^{205}\mathrm{Tl}$ becomes beta-radioactive, decaying to $^{205}\mathrm{Pb}$

$$^{81}\mathrm{Tl}_{205} \rightarrow {}^{82}\mathrm{Pb}_{205} + {}^{-1}\mathrm{e}_0 + \bar{\mathrm{u}}$$
