Description

The size of an atom is only a few angstroms at most - there are 10 billion angstroms in 1 meter. This video also goes the basic parts of an atom (protons, neutrons, and electrons) and why the traditional model of the atom is not correct. Electrons are unpredictible - we can't know the path that they travel. Most importantly - they don't orbit the nucleus.

For the curious minded:
-Heisenburg Uncertainty Principle states that the position and velocity cannot both be measured at the same time
-The orbital is only about a 95% probability of finding the electron - it could still be found outside.
-Electrons can even be described as a wave (in addition to a particle) occupying the whole orbital at once.
