Analogy Experiment—Projectile Pennies with Rutherford

Ben Meacham | Mon, 11/08/2021 - 15:48

Atomic theory is a common topic throughout any introductory chemistry course. It is likely that Rutherford’s gold foil experiment gets at least some attention in your course. This simple activity gives students an opportunity to replicate Rutherford’s experiment through an analogy experiment that may allow for easier conceptualization of the experiment itself and provide additional support for model development.

Atomic theory is a common topic throughout any introductory chemistry course. It is likely that Rutherford’s gold foil experiment gets at least some attention in your course. I have used a simple activity that gives students an opportunity to replicate Rutherford’s experiment through an analogy experiment that may allow for easier conceptualization of the experiment itself and provide additional support for model development.

The Atomic Dashboard

If you are on Twitter and follow #chemchat, you may have recently seen some beautiful, rotating 3D atomic and molecular models from Dave Doherty @atomsNMolecules. I was curious about these models and after contacting Dave, he introduced me to The Atomic Dashboard.

Using Orbital Viewer

Orbital Viewer is a fantastic program for displaying electronic orbitals. It is a great resource for teaching students about orbital shapes and the rules, nomenclature and notation of the quantum numbers n, l and m.
