A certain radionuclide is used to diagnose lymphoma. An atom of this radionuclide contains 31 protons and 36 neutrons. Which statement is correct about the radionuclide?

A.The atomic number is 31, the mass number is 67, and its symbol is 67/31 GA.

Explanation:

Statements are:

A.The atomic number is 31, the mass number is 67, and its symbol is 67/31 GA.

B.The atomic number is 31, the mass number is 67, and its symbol is 31/64 GA.

C.The atomic number is 67, the mass number is 31, and its symbol is 67/31 GA .

D.The atomic number is 67, the mass number is 31, and its symbol is 31/64 GA .

Atomic number is defined as the number of protons in an atom. The radionuclide has 31 protons. Its atomic number is 31. C and D are FALSE

In the nuclear notation, in the top you have mass number = Sum of protons + neutrons = 67. And in the bottom you have atomic number = 31.

Thus, right statement is:
