How many neutrons are in tin?
Understand the Problem
The question is asking for the number of neutrons in the element tin. Tin has several isotopes, but the most common isotope has 50 neutrons. To determine the number of neutrons, you would typically subtract the atomic number (which is 50 for tin) from the mass number of the isotope in question.
Answer
69 neutrons
The most common isotope of tin has 69 neutrons
Answer for screen readers
The most common isotope of tin has 69 neutrons
More Information
Tin has multiple stable isotopes, which can have varying numbers of neutrons. The most common isotope, tin-119, has approximately 69 neutrons.
Tips
When calculating neutrons in an isotope, always subtract the atomic number (protons) from the mass number (total protons and neutrons).
