Answer : Beta particle will balance the following nuclear equation.
Explanation :
The nuclear reaction is,
[tex]^{234}_{91}Pa\rightarrow ^{234}_{92}U+^{-1}_0\beta[/tex]
Beta particle : It forms when a neutron changes into a proton and a high-energy electron.
When the nucleus emits the beta particle, the mass number remains same and the atomic number increases by 1 and the nuclear charge increases by 1.
Hence, the Beta particle will balance the following nuclear equation.
