About Subatomic Particles
- Subatomic particles include all fundamental particles as well as some other low mass particles made from a combination of fundamental particles.
- Some subatomic particles you should know are:
- Leptons - Fundamental particles
- Quarks - A group of subatomic particle believed to be fundamental but have never been on their own. They always exists in either a triplet of quarks or a quark-antiquark pair.
- Hadrons - Subatomic particles made of quarks.
- Bosons - Subatomic particles which mediate the fundamental interactions.
- Photon - A type of boson which mediates the electromagnetic interaction.
- W-boson - A type of boson which mediates the weak nuclear interaction.
- Z-boson - A type of boson which mediates the weak nuclear interaction.
