Key Stage 4
Meaning
The Proton is a positively charged particle found in the nucleus of an atom.
About Protons
- Protons are a type of nucleon.
- Protons have a relative atomic charge of +1 and a relative atomic mass of 1.

| This atom has an Atomic Number (Z) of 1 therefore it contains 1 proton. | This atom has an Atomic Number (Z) of 2 therefore it contains 2 proton. | This atom has an Atomic Number (Z) of 3 therefore it contains 3 proton. | This atom has an Atomic Number (Z) of 4 therefore it contains 4 proton. |
Key Stage 5
Meaning
A proton (p) is a baryon made from 2 up-quarks and 1 down-quark.
About Protons
- A proton is one of two baryons found in the atomic nucleus.
- Protons have a charge of 1.60x10-19 Coulombs (the elementary charge) and a mass of 1.67x10-27kg.
- A proton is the most stable hadron with a half life longer than the age of the Universe.
