Lesson Topic
atomic number and mass
Lesson Outline
Review determination of the atomic number as the number of protons, and the atomic mass as protons plus neutron found in the nucleus.
Elicit a formula for finding the number of neutrons given the atomic number and the atomic mass.
Show how the information for an atom is designated in the atomic symbol box for each atom.
Discuss isotopes and the difference between atomic mass and atomic mass units.
Have Ben solve 2-3 problems determining the atomic mass, the number of protons and electrons, and the number of neutrons only.
