Where does evidence for the existence of quarks come from?

High energy collisions carried out in particle accelerators

Evidence for the existence of antimatter

The production of energy in the annihilation of particles

What was the first evidence of the neutrino?

Beta decay

What is beta decay?

When a fast moving electron is ejected from the nucleus

What changes after an element goes through beta decay

Atomic number +1

How many quarks are baryons made up of?

3

When calculating the charge of quarks. What must be remembered?

That the charge is relative to the charge of an electron, therefore the calculated charge must be multiplied by the charge of an electron.
