Review: Rutherford’s ModelReview: Rutherford’s Model
• the nucleus of the atom is composed of protons and neutrons.
• That the nucleus is small
• The electrons are circling the nucleus.
Rutherford’s FailureRutherford’s Failure
• He couldn’t explain why the negative electrons aren’t attracted into the positive nucleus, causing the atom to collapse.
• Video 15:15
A Strange Answer A Strange Answer to a Strange Questionto a Strange Question
• Why doesn’t the electron fall into the nucleus?
• Because it isn’t allowed!
To understand this unbelievable phenomenon, we must understand the nature of light
Neils Bohr
We are all agreed that your theory is crazy. The question which divides us is whether it is crazy enough to have a chance of being correct. My own feeling is that it is not crazy enough.
