Answer for screen readers
The lightest known particle is the neutrino
More Information
Neutrinos are elementary particles with extremely small masses, much smaller than electrons, and they interact only via the weak nuclear force and gravity, making them very difficult to detect.
Tips
A common mistake is to confuse the lightest stable particle, the electron, with the lightest known particle, the neutrino.
