What students need to be able to do

Use average atomic mass, isotopes, mass number, and atomic number to describe and compare elements.
Describe and analyze nuclear decay.
Use trends within groups and periods including atomic radii, electronegativity, shielding effect, and ionization energy to predict element properties.
Use electron configurations, valence electrons, excited electrons, and ions to explain chemical behavior.
Describe historical and quantum models of the atom.
