Which subatomic particle carries a negative electrical charge?

Which subatomic particle carries a negative electrical charge?

• A. Proton
• B. Electron
• C. Neutron
• D. Positron

Answer: (B)

Electric charge comes in positive and negative forms, and the particle with negative charge is the electron. Protons carry a positive charge, neutrons have no charge, and positrons are the positively charged antiparticles of electrons. The electron’s charge is equal in magnitude to the proton’s but opposite in sign, about -1 elementary charge, which is why it’s the negative-charge subatomic particle commonly involved in chemical bonds and electrical currents.
