This image is a representation of the Standard Model, probably the closest thing we have to a theory of everything. At least... everything we know about!
- Why are solids solid when atoms are mostly empty space?
- What are the fundamental forces of nature?
- Why hasn't a single quark ever been observed?
- Why does releasing energy make a nucleus more stable?
It´s impossible to draw an atom without promoting misconception. If the nucleus were a dot the electrons would´t fit on the page.
In this course there are few surprises, experiments usually verify the theory. When Rutherford saw the results of the scattering experiment he was very surprised, the result was not inline with the theory at all. Without surprise results science would not
Binding energy is often wrongly defined as the energy that holds a nucleus together. The nucleus is held together by the nuclear force. BE is the energy require to separate the nucleons. BE is not possessed by the nucleus it was released when the nucle
Most of this topic is based on an understanding of the BE/nucleon vs nucleon graph but to understand that you have to understand binding energy....
Radiation was classified as alpha beta and gamma due to the different properties. Now we know they are Helium nuclei, electrons and photons. Maybe it´s time to drop the Greek labels.
The basic principle behind the working of a nuclear power station. There will be more about this later.
