The fundamental particle that has the least mass is the electron.
Answer for screen readers
The fundamental particle that has the least mass is the electron.
More Information
The electron has a significantly lower mass than protons and neutrons, which are found in the nucleus of an atom. The electron mass is about 1/1840 of a proton's mass.
Tips
A common mistake is confusing the mass of neutrons and protons with electrons. Remember electrons have a negligible mass compared to the others.
