------------------------------------------------ Determine the number of protons and the number of neutrons in an atom of Sn-118.

A. 118 protons, 118 neutrons
B. 68 protons, 50 neutrons
C. 50 protons, 68 neutrons
D. 50 protons, 118 neutrons

Answer :

Final answer:

In an atom of Sn-118, there are 50 protons and 68 neutrons, which is option c) of the question.

Explanation:

The number of protons and neutrons in an atom of Sn-118 can be determined by examining its atomic number and mass number. The atomic number of tin (Sn) is 50, which means that every tin atom has 50 protons in its nucleus. The mass number of the Sn-118 isotope is 118. To find the number of neutrons, we subtract the number of protons from the mass number: 118 - 50 = 68 neutrons. 50 protons and 68 neutrons is, thus, the right response (c).
