Protons have a much greater mass than electrons.

Here's a breakdown:

* Proton: A proton is a subatomic particle found in the nucleus of an atom. It carries a positive charge and has a mass of approximately 1.6726 × 10^-27 kg.

* Electron: An electron is a subatomic particle that orbits the nucleus of an atom. It carries a negative charge and has a mass of approximately 9.1094 × 10^-31 kg.

Therefore, a proton is about 1836 times heavier than an electron.
