This Is Not What an Atom Looks Like
What does an atom look like? Throughout history scientists and philosophers have attempted to answer this question. As a result, they've come up with some useful models for understanding the building blocks of our universe.

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...

Quantum Mechanical Model
In this video Paul Andersen explains how the quantum mechanical model of the atom refined the shell model. Uncertainty of the position of the electron as well as spin forces chemists to create an improved model. In this model the...

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...

Quantum Mechanics | The Bohr Model of the Atom
What are the issues with the Bohr model of the atom (Neils Bohr)? Some issues with this mode helped early physicists invent and develop the discipline of quantum mechanics.

The Atomic Model
Everything is made of Atoms and the number of electrons and neutrons an atom has determine what form it will take. This class dresses up as the components of an atom to demonstrate the Atomic Model. Great for kinesthetic and visual...
