검증된 단계별 안내1
Recall that subatomic particles include protons, neutrons, and electrons, each with distinct electric charges.
Understand that a proton is a particle found in the nucleus of an atom.
Remember the charge characteristics: electrons have a negative charge, neutrons have no charge (neutral), and protons have a positive charge.
Recognize that the charge of a proton does not vary with isotopes; isotopes differ in neutron number, not proton charge.
Conclude that the proton's electric charge is positive.
