Atoms, Molecules, and Ions

This quiz covers a range of topics related to isotopes, including their identification, and calculating properties like protons, neutrons, electrons, average atomic mass, and percent abundance.



These are some examples of the question types found in the quiz:

  • Identifying Isotopes Definition of isotopes. A. Given the symbol of an element (e.g., carbon), identify its isotopes. B. Recognize the notation for isotopes (e.g., carbon-12, carbon-13, carbon-14). C. Differentiate between isotopes of the same element based on their atomic number and mass number.
  • Calculating Protons, Neutrons, and Electrons A. Determine the number of protons in an isotope based on its atomic number. B. Calculate the number of neutrons by subtracting protons from the mass number. C. Understand how electrons are distributed in isotopes based on their atomic number.
  • Calculating Average Atomic Mass A. Define the average atomic mass. B. Calculate the average atomic mass of an element given the percent abundance of its isotopes and their respective masses. C. Practice calculating the average atomic mass for various elements.
  • Percent Abundance of Isotopes A. Explain what percent abundance represents in the context of isotopes. B. Calculate the percent abundance of individual isotopes from experimental data. C. Use the percent abundance to calculate the average atomic mass.
