Question

which subatomic particles attract electrons, causing them to keep orbiting the nucleus?
○ electrons
○ protons
○ neutrons
○ nuclei

Explanation:

To solve this, we recall subatomic particle charges: electrons are negative, protons are positive, neutrons are neutral, and nuclei are collections of protons/neutrons. Opposite charges attract, so positive protons in the nucleus attract negative electrons, keeping them in orbit. Electrons repel electrons, neutrons have no charge to attract, and nuclei (as a whole) include neutrons, so protons are the correct subatomic particle here.

Answer:

B. protons
