Verified step by step guidance1
Recall the basic structure of an atom: it consists of a nucleus containing protons and neutrons, with electrons orbiting around the nucleus.
Understand the charges of subatomic particles: protons carry a positive charge, electrons carry a negative charge, and neutrons are neutral.
Compare the locations of protons and electrons: protons are located inside the nucleus, while electrons are found outside the nucleus in electron clouds or orbitals.
Consider the masses of protons and electrons: protons have a much greater mass compared to electrons, which are very light.
Evaluate each statement based on these facts to determine which one correctly describes the proton and electron.
