Protons and  Neutrons make up the nucleus. They have a mass of 1 relative to each other but an actual mass of 1.67 x 10-27kg. The proton carries a charge of +1.6 x 10-19C. In certain calculations you must use the actual values.
Are negatively …

In 1887, the German physicist Heinrich Rudolf Hertz discovered an interesting property of matter.
This property is that physical materials emit charged particles when they absorb radiant energy (eg, light). Of course, not all substances absorb radiant energy, and the ones that don’t will …

1 Matter Radiation

This is a topic which introduces the detail of the atom, the idea of stability, the photon model E = hf, antiparticles and the interactions of particles. There is quite a lot of wordy detail and basic facts to learn with a small number of calculations such as specific charge or E = hf to …

2 Quarks and leptons

 This topic is about learning what is inside a nucleus and essentially how does that make an atom behave. You really need to learn a lot of basic facts.  You can also find loads of youtube movies, just search for the key terms and you will learn lots of things.

3 Quantum phenomena

This chapter covers the quantum phenomena of the photoelectric effect, excitation, fluorescence and line spectra. What is most important is to learn the ideas of photoelectric effect so you can construct a wordy answer to a 6-7 mark written question. Also make sure you know your Joules from your eV’s. Finally there are a lot …

Chapter 02 Quarks & Leptons

Use these quick notes to help you revise each topic from the Chapter.

In 1934 Hideki Yukawa predicted the existence and the approximate mass of a particle call the “meson” as the carrier of the strong force that holds the atom together.  Yukawa called his carrier particle the meson, from mesos, the Greek word for intermediate, because its predicted mass was between …
