검증된 단계별 안내1
Recall that the electron is a fundamental subatomic particle found in atoms.
Understand that the charge of an electron is a fundamental property and is always the same.
Remember that the electron carries a charge opposite to that of a proton.
Recognize that the proton has a positive charge, so the electron must have a negative charge.
Conclude that the best description of the electron's charge is 'Negative'.
