Which statement correctly describes the location, charge, and mass of neutrons in an atom?

• A. Neutrons are located in the nucleus, have a positive charge, and have a mass much greater than protons.
• B. Neutrons are located in the electron cloud, have a negative charge, and have a much smaller mass than protons.
• C. Neutrons are located in the electron cloud, have no charge, and have a mass nearly equal to that of electrons.
• D. Neutrons are located in the nucleus, have no charge, and have a mass nearly equal to that of protons.

Answer: (D)

Verified step by step guidance

1. Recall the structure of an atom, which consists of a nucleus at the center and an electron cloud surrounding it.
2. Identify the location of neutrons: Neutrons are found inside the nucleus along with protons.
3. Understand the charge of neutrons: Neutrons have no electric charge; they are neutral particles.
4. Compare the mass of neutrons to other subatomic particles: Neutrons have a mass nearly equal to that of protons, which is much greater than the mass of electrons.
5. Combine these facts to correctly describe neutrons: They are located in the nucleus, have no charge, and have a mass nearly equal to protons.
