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.
Key Stage 5
Meaning
A proton is a baryon made from 2 up-quarks and 1 down-quark.
About Protons
- Protons have 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.
