True, the proton has greater mass than an electron.
Explanation:
- The fundamental unit of matter is the atom. It can be divided into sub-particles called proton, neutron and electron.
- Protons and neutrons are found in the nucleus while electrons are present in the orbits around the nucleus.
- A proton has a mass of 1.674929 x 10^-27 kg while the electron has a mass of 9.109390 x 10^-31 kg.
- So the proton is heavier than the electron.
