Verified step by step guidance

1. Recall the basic properties of subatomic particles: protons, neutrons, and electrons.
2. Understand that protons are positively charged particles found in the nucleus of an atom.
3. Know that neutrons are neutral particles, meaning they have no charge, and are also located in the nucleus.
4. Recognize that electrons are negatively charged particles that orbit the nucleus.
5. Compare each statement with these properties to identify the correct one: 'Protons have a positive charge.'
