Quizplus · Accepted Answer

The atomic number of tin (Sn) is 50, which means it has 50 protons and 50 electrons in a neutral atom. The mass number of tin is 118, which is the sum of protons (50) and neutrons. Therefore, the number of neutrons in a neutral atom of tin is 118 - 50 = 68. Hence, the correct answer is C: 50 protons, 68 neutrons, and 50 electrons.
