The final answer is the electron
More Information
The electron is nearly massless and carries a negative charge. Its rest mass is approximately 9.11 × 10^-31 kg, much smaller than that of protons and neutrons.
Tips
A common mistake is confusing the electron with the positron. Both have the same mass, but a positron is a positively charged particle.
