Answer:
d
Explanation:
- The proton is about 1,836 times as heavy as the electron; nobody knows why nature picked that particular number. The neutron is very slightly heavier than the proton, by about 0.1%, or 1.00137841887 according to the best measurements.
Electrons weight less than protons so that incorrect A❌
Protons weight less than neutrons but more than electrons B.❌
protons don’t weigh more than neutron C❌
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.
