Question

Quizplus · Accepted Answer

The atomic number of an atom is determined by the number of protons in its nucleus. In 13_C, represents the number of protons of each element present in the atom. Thus, the atomic number can be determined by adding up the number of protons for each element: S (1) + U (1) + B (0) + C (0) = 2. This corresponds to element number 2, which is carbon (C). Therefore, the best choice is B.
