Model Simulation (Chemistry) – Isotopes and Atomic Mass

Topics

• Isotopes
• Atomic Mass

Sample Learning Goals

• Define “isotope” using mass number, atomic number, number of protons, neutrons and electrons.
• Given information about an element, find the mass and name of an isotope.
• Give evidence to support or dispute: “In nature, the chance of finding one isotope of an element is the same for all isotopes.”
• Find the average atomic mass of an element given the abundance and mass of its isotopes.
• Predict how the mass and name of an isotope will change given a change in the number of protons, neutrons or electrons.
• Predict how the average atomic mass of an element changes given a change in the abundance of its isotopes.
