The atomic number of a neutral atom is equal to the number of protons and the number of electrons of the atom. The atomic weight meanwhile is equal to the sum of the number of protons and number of neutrons. Isotopes differ in the number of neutrons but the number of protons remain the same. In this case, the answer is B
