Use information from the diagram and your knowledge of physics to answer the following questions. (a) Explain why particles such as leptons and quarks are known as Fundamental Particles. (b) A particle called the sigma plus ( +) has a charge of +1. It contains two different types of quark. It has two up quarks each having a charge of + 2 / 3
Quarks are a type of fundamental particle which combine to form hadrons such as protons and neutrons. There are six flavours (types) of quark: up, down, top, bottom, strange, and
At the centre of an atom is a nucleus formed of protons and neutrons, therefore they are known as nucleons, whereas electrons orbit the nucleus in shells. The specific charge of a particle is the charge-mass ratio, and is calculated by dividing a particle’s charge by its mass.

Six known quarks exist: up (u), down (d), charm (c), strange (s), top (t), and bottom (b). These particles are fermions with half-integral spin and fractional charge. Baryons consist of three quarks, …
The standard model of particle physics is a mathematical model that describes electromagnetism, the strong and weak nuclear forces, and the Higgs mechanism.
