Electrons Back to Game

Milliken’s experiment, which determined the charge on an electron, was named this What is…? Atomic Discoveries for $200

Oil Drop Experiment Back to Game

In Rutherford’s gold foil experiment, a few alpha particles bounced off the gold due to their collision with this What is…? Atomic Discoveries for $300

Gold atom’s nucleus Back to Game

Dalton’s idea that all atoms of a given element are identical was defeated by the discovery of these What are…? Atomic Discoveries for $400

Isotopes Good Answer! Back to Game

Milliken’s ability to use his results to determine the charge on an electron depended on the results of this experiment What is…? Atomic Discoveries for $500

Back to Game Cathode Ray Tube (CRT) Experiment

What is…? Atomic Models for $100 In the solar system model of the atom, protons are found in this location

The nucleus Back to Game

What is…? Atomic Models for $200 In this atomic model, negatively charged electrons are embedded in a large, positively charged atom

Thompson’s Plum Pudding (Chocolate Chip Cookie) Model Back to Game

What are…? Atomic Models for $300 Bohr assigned electrons to these to explain why they didn’t fall into the nucleus

Energy levels, OR orbits Back to Game

What are…? Atomic Models for $400 In the quantum mechanical model, electrons can be found in these regions around the nucleus

orbitals Back to Game

What is…? Atomic Models for $500 The quantum mechanical model of the atom uses this math principle to develop the idea of orbitals
