2.1 The nuclear atom

Experiments

Here are experiments our science specialists have selected to support the IB* topic.

Recommended

α, β, and γ

Experiment #27 from Advanced Chemistry with Vernier

In this experiment, you will

  • Develop a model for the relative absorption of alpha, beta, and gamma radiation by matter.
  • Use a radiation counter to measure the absorption of alpha, beta, and gamma radiation by air, paper, and aluminum.
  • Analyze the count rate data to test for consistency with your model.

Recommended

Radiation Shielding

Experiment #28 from Advanced Chemistry with Vernier

In this experiment, you will

  • Develop a model for the absorption of beta radiation by matter.
  • Use a radiation counter to study how the radiation emitted by a beta source is absorbed by cardboard.
  • Test the model against experimental data to determine its validity.

Nuclear Radiation

Experiment #25 from Investigating Chemistry through Inquiry

In this Preliminary Activity, you will use a radiation monitor to determine the absorption of beta radiation by paper and by aluminum.

After completing the Preliminary Activity, you will first use reference sources to find out more about nuclear radiation before you choose and investigate a researchable question.
