Guida verificata passo dopo passo1
Recall the three main subatomic particles: protons, neutrons, and electrons.
Understand that the mass of a proton and a neutron is approximately 1 atomic mass unit (amu), which is much larger than the mass of an electron.
Know that the electron's mass is about 1/1836 that of a proton or neutron, making it significantly lighter.
Compare the masses: proton ≈ neutron > electron.
Conclude that the electron has the least mass among the three subatomic particles.
