What Are The Different Atomic Models? Dalton, Rutherford, Bohr and Heisenberg Models Explained
Atomic Models: Centuries ago, people didn’t know exactly what was inside an atom, but they had some “ideas”. Around 400 BC, a Greek philosopher named Democritus came up with a theory that everything in the world was made of tiny...

Atomic Models
In this video Paul Andersen explains how the atomic model has changed over time. A model is simply a theoretical construct of phenomenon and so when we receive new data we may have to refine our model. Ionization energy data resulted in...
