Guida verificata passo dopo passo1
Identify the subatomic particles mentioned: alpha particle, proton, electron, and neutron.
Recall that an alpha particle consists of 2 protons and 2 neutrons, so its mass is roughly 4 times that of a proton or neutron.
Understand that protons and neutrons have similar masses, both significantly greater than that of an electron.
Recognize that the electron is a fundamental particle with a mass approximately 1/1836 that of a proton or neutron.
Conclude that among the given options, the electron has the least mass.
