Is the following nuclear equation balanced?
234/90 th —> 0/-1 e + 234/91 pa

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 = 90On 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

Ithink the answer is c i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you
