Identify isotopes by determining the number of neutrons in the nucleus. Isotopes of an element have the same number of protons but different numbers of neutrons. For example, Carbon-12 has 6 protons and 6 neutrons, while Carbon-14 has 6 protons and 8 neutrons. Use the atomic number (protons) and subtract it from the atomic mass to find the number of neutrons.

FAQs & Answers

  1. What is an isotope? An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons in its nucleus.
  2. How do you find the number of neutrons in an isotope? To calculate the number of neutrons in an isotope, subtract the atomic number (which represents the number of protons) from the isotope's atomic mass.
  3. Can an element have more than two isotopes? Yes, many elements have multiple isotopes. For example, carbon has several isotopes, including Carbon-12, Carbon-13, and Carbon-14.
  4. Why are isotopes important in science? Isotopes are significant in various fields, including chemistry, medicine, and geology, as they are used for dating materials, medical imaging, and understanding chemical processes.
