Which particle has a positive charge and is located in the nucleus?

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

Answer: (A)

In atomic structure, the nucleus contains protons and neutrons. Protons have a positive electric charge and reside in the nucleus, defining the element’s identity and contributing to the nucleus’s overall positive charge. Neutrons are neutral, adding mass but no charge. Electrons orbit the nucleus and carry negative charge. A positron is a positively charged particle, but it is not part of the nucleus in ordinary atoms. Therefore, the particle with a positive charge located in the nucleus is the proton.
