PHYS - Geiger-Mardsen Experiment
Physics, alpha particle, structure of atom, Geiger-Mardsen experiment - IBDP | DSE | GCE | IAL | AP Physics
Two scientists, Geiger and Mardsen, used alpha particles in a very famous experiment to determine the structure of atoms!
When a beam of alpha particles was aimed at the thin gold foil in a vacuum...
Why is it important that the experiment was done in vacuum?
Just a quick recap on what an alpha particle is:
For IGCSE Physics, it is important to understand the conclusions drawn from this experiment!
Based on the observations from the experiment, scientists concluded that each atom has a small, dense, positively-charged nucleus. How did the scientists come up with this conclusion? 🤔
