Verified step by step guidance

Identify the subatomic particles mentioned: neutron, electron, proton, and photon.

Recall the basic properties of each subatomic particle: Neutrons are neutral, electrons are negatively charged, protons are positively charged, and photons are particles of light with no charge.

Understand the structure of an atom: The nucleus contains protons and neutrons, while electrons orbit the nucleus.

Determine which subatomic particle is located in the nucleus and has a positive charge. From the properties, protons are the particles that fit this description.

Conclude that the subatomic particle found in the nucleus with a positive charge is the proton.
