Which of the following correctly describes a proton?
Positively charged particle
A proton is a sub-atomic particle found in the nucleus of an atom.
It carries one unit of positive charge (+1.6 × 10-19 C) and has a mass of about 1 u.
The electron is negatively charged and the neutron is neutral, and neither the proton nor the neutron is massless.
Hence, the answer is a positively charged particle.
