What happens to electrons in terms of attraction and repulsion?

• A. Electrons attract other electrons and attract protons.
• B. Electrons repel other electrons and attract protons.
• C. Protons repel electrons and attract neutrons.
• D. Electrons repel protons and attract neutrons.

Answer: (B)

The main idea is how electrical charges interact: opposite charges attract, like charges repel. An electron is negatively charged and a proton is positively charged, so they attract each other. Electrons also repel other electrons because they share the same negative charge. Neutrons have no electric charge, so they don’t exert electrostatic attraction or repulsion with electrons or protons.

This is why the statement that electrons repel other electrons and attract protons is correct: it reflects both parts of Coulomb’s law—same charges repel, opposite charges attract. The other options contradict these basic charge interactions (for example, protons do not repel electrons; neutrons carry no charge to be attracted or repelled).
