Which of the following correctly defines one of the components of an atom?

• A. An electron is a positively charged particle located in the nucleus.
• B. A proton is a neutral particle found outside the nucleus.
• C. A proton is a positively charged particle found in the nucleus of an atom.
• D. A neutron is a negatively charged particle found outside the nucleus.

Answer: (C)

Verified step by step guidance

1. Recall the three main subatomic particles that make up an atom: protons, neutrons, and electrons.
2. Understand the charge and location of each particle: Protons have a positive charge and are located in the nucleus; neutrons have no charge (neutral) and are also located in the nucleus; electrons have a negative charge and orbit outside the nucleus.
3. Evaluate each statement based on these properties: Check if the charge and location described match the known characteristics of each particle.
4. Identify the correct statement: The one that correctly pairs the particle with its charge and location within the atom.
5. Conclude that the correct definition is: 'A proton is a positively charged particle found in the nucleus of an atom.'
