Which statement correctly describes protons and neutrons?

• A. Both protons and neutrons have a negative charge.
• B. Protons and neutrons are found outside the nucleus.
• C. Neutrons have a positive charge, while protons are neutral.
• D. Protons have a positive charge, while neutrons are neutral.

Answer: (D)

Verified step by step guidance

1. Recall the basic structure of an atom, which consists of a nucleus containing protons and neutrons, and electrons orbiting around the nucleus.
2. Understand the charge of each subatomic particle: protons carry a positive charge, neutrons have no charge (they are neutral), and electrons carry a negative charge.
3. Recognize that both protons and neutrons are located inside the nucleus of the atom, not outside.
4. Evaluate each statement given in the problem by comparing it to the known properties of protons and neutrons.
5. Conclude that the correct description is: 'Protons have a positive charge, while neutrons are neutral,' because this matches the established scientific understanding of these particles.
