검증된 단계별 안내1
Recall the three main subatomic particles: electrons, protons, and neutrons, and their basic properties.
Understand that electrons have a very small mass and carry a negative charge.
Know that protons have a significant mass (about 1 atomic mass unit) and carry a positive charge.
Recognize that neutrons have a mass similar to protons but carry no electric charge, making them neutral.
Conclude that the particle with appreciable mass and no charge is the neutron.
