Question

Compare the mass of electron(e), Proton (p) and Neutron (n).​

Answer 1

Answer:

Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron.

Answer 2

Answer:

e/m for electron is 1/0 (as electron has negligible mass), for proton is 1/1, for neutron is 0/1, and for alpha particle is 2/4 or 1/2. ... The mass unit (amu) for e is almost 0, fro p is 1, for neutron is 1, and for alpha particles is 4.
