A
Another electron (negative charge)
B
A positively charged nucleus in general
C
A proton (positive charge)
D
A neutron (no charge)
검증된 단계별 안내1
Understand that electrostatic (Coulombic) forces describe the attraction or repulsion between charged particles based on their charges.
Recall that electrons carry a negative charge, so they repel other particles with the same negative charge due to like charges repelling each other.
Identify that a positively charged nucleus or proton would attract an electron because opposite charges attract.
Recognize that neutrons have no charge, so they neither attract nor repel electrons via electrostatic forces.
Conclude that an electron repels another electron because both have negative charges, leading to electrostatic repulsion.
