Which particles in an atom could demonstrate that opposite charges attract?
2 answers:
Answer:
Choice D. a proton and an electron.
Explanation:
Each proton carries a positive charge of unit.
Each electron carries a negative charge of unit.
As their name suggests, neutrons are neutral. They do not carry any electrostatic charge. Because of that, neutrons can't attract or repel neutrons or protons with electrostatic forces.
On the other hand, electrons and protons carry opposite charges. Therefore, an electron and a proton would attract each other electrostatically.
However, since protons are all positive, two protons would repel each other electrostatically.
