검증된 단계별 안내1
Recall the basic properties of subatomic particles: protons, neutrons, and electrons.
Understand the location of each particle: protons and neutrons are located in the nucleus, while electrons are found outside the nucleus.
Compare the masses of the particles: protons and neutrons have similar masses, which are much greater than the mass of an electron.
Review the charges of the particles: protons have a positive charge, electrons have a negative charge, and neutrons are neutral.
Use this information to evaluate each statement and identify the one that correctly describes the properties of subatomic particles.
