Bohr's Atomic Model: Electrons in Orbit
In 1913, Niels Bohr proposed an atomic model that dramatically altered our comprehension of atomic structure by establishing a novel framework for describing the arrangement and behaviour of electrons within an atom. The purpose of...

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...

Charges in Atoms, Atomic Models, and Quantum Numbers
This video explains how the different particles in an atom have charges, how the different particles affect the overall charges of an atom, and how atomic models are created.

Practice Problem: The Bohr Model and Photon Wavelength
With the Bohr model we start to get a better sense of the nature of matter, particularly the way light interacts with atomic matter such that we can see it. But how do we do calculations regarding these interactions? Let's practice now!
