C) 24

Explanation:

When a radioactive isotope of Vanadium, V decays by producing a beta particle and gamma rays, the atomic number will be 24.

Vanadium is the 23rd element on the periodic table.

It has a mass number of 51.

atomic number is 23

⁵¹₂₃V

A beta particle is symbolized as °₋₁B

Gamma rays are represented by Y

Now to the equation:

⁵¹₂₃V → ₐⁿK + °₋₁B + Y

In a nuclear reaction the mass an atomic number is conserved

51 = n + 0

n = 51

23 = a -1

a = 24

We can see that the nuclide formed will have an atomic number of 24
