Answer:
Yes, the nuclear equation is balanced
Step-by-step explanation:
We are given the nuclear equation;
²³⁴₉₀Th → ⁰₋₁e + ²³⁴₉₁Pa
- The nuclear equation balanced as the mass number and atomic number are equal on both side of the equation.
- That is; Reactant side, Mass number = 234 , atomic number = 90
- On the product side, Mass number = 234 + 0 = 234,
Atomic number = -1 + 91 = 90
- The nuclear equation shows beta decay.
- When a radioactive nuclide undergoes decay, the mass number remains the same and the atomic number increases by 1.
- In this case, Thorium undergoes beta decay to protactinium
