In nature most elements occur as a mixture of two or more isotopes. Eachisotope of an element has a fixed mass with a natural percent abundance. The mass of theelement needs to reflect the masses of these isotopes in their respective abundances. Giventhe masses and abundances, how is the Average Atomic Mass determined?
In this activity, you will determine the atomic mass of the fictitous element Candium.

This activity utilizes an online interactive simulation (PhET.colorado.edu) that allows students to explore and manipulate the subatomic particles that comprise the atom. Students also explore atomic mass, ions, nuclear symbols, and the periodic table. A link to the simulation and a downloadable file that includes a pre-lab, a student activity guide, and a post-lab assessment. The simulation also includes other inquiry opportunities and a game.
