Ch. 8 Atomic Theory

8.B Protons, Neutrons, and Electrons

Simulation: Protons and Electrons

Lesson & Practice:: Khan Academy

8.C Isotopes and Ions

Simulation:: Create your own isotopes by adding neutrons to stable atoms.

Practice:: Make your own quiz!

• Click first 3 checkmarks under "Question Types --> Elements"

• Decide if you'd like the quiz to include ions

8.D Average Atomic Mass

Lesson & Practice: Video and practice (Pearson)

Practice: Make your own quiz!  You may want to change the precision of masses to the hundredths or thousandths place.

8.E Radiation and Nuclear Decay

Practice: Make your own quiz!  Uncheck "Half-Life Calculations" and only keep "Alpha decay" and "Beta (minus) decay" checked. (ChemQuiz.net)

Practice:: Alpha, beta, and gamma decay (Khan Academy)

Game: Radioactive decay (eChalk)

8.E Fission vs. Fusion

Simulation: Nuclear Fission (PhET)

Practice: Nuclear Fission problems (Khan Academy)

Practice: Nuclear fission/fusion and nuclear reactors

8.F Half-life

Simulation:: radioactive decay of 400 radioactive nuclei.

Lesson & Practice:: Half-life (Khan Academy)

Practice:: Radioactivity half-life quiz (Isaac Science)

Practice:: Make your own quiz!  Uncheck "Nuclear Reactions" and keep "Half-life calculations" checked. (ChemQuiz.net)
