Bean Bag Isotopes: Relative Abundance and Atomic Mass—ChemTopic™ Lab Activity

firewatch

The discovery of radioactivity in the early 20th century made it possible to study the actual structure and mass of atoms, which led to the discovery of isotopes, atoms of the same element with different masses. With the Bean Bag Isotopes: Relative Abundance and Atomic Mass—ChemTopic™ Lab Activity, investigate the mass properties and relative abundance of isotopes for the “bean bag” element and calculate its atomic mass.

Concepts

  • Isotope
  • Mass Number
  • Percent Abundance
  • Atomic Mass
