Answer:

Yes, the nuclear equation is balanced

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

yes
