They are really hard to catch to put on a scale.

electron mass = 9.10938188 × 10-31 kilograms
proton mass = 1.67262158 × 10-27 kilograms
neutron mass = 1.67492716 × 10-27 kilograms

Protons and neutrons are very close, and are generally what is
considered when calculating molecular weight. Protons and neutrons are
about 2000 times as massive as electrons. The difference in weight
between a proton and a neutron is several times the weight of an
electron.
