Part A. p, n = 31, 38.

Part B. p, n = 31, 40.

Part C.

Explanation:

Hello,

Part A.

In this case, since the atomic number for gallium is 31, we can say that the first isotope has also 31 protons and the neutrons are computed by using its molar mass as a whole number (69):

Thus, result is p, n = 31, 38.

Part B.

In this case, since the atomic number for gallium is 31, we can say that the second isotopes has also 31 protons and the neutrons are computed by using its molar mass as a whole number (71):

Thus, result is p, n = 31, 40.

Part C.

Finally, the isotopes as shown as:

Best regards.
