Which subatomic particle is characterized by a positive electrical charge and is found in the nucleus of an atom?

• A. Proton
• B. Positron
• C. Neutron
• D. Electron

Answer: (A)

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 of each particle: protons have a positive charge, neutrons have no charge (neutral), and electrons have a negative charge.
3. Identify the location of each particle within the atom: protons and neutrons are located in the nucleus, while electrons orbit around the nucleus.
4. Since the question asks for a subatomic particle with a positive charge found in the nucleus, focus on particles in the nucleus with positive charge.
5. Conclude that the particle characterized by a positive electrical charge and found in the nucleus is the proton.
