Verified step by step guidance

1. Recall the three main subatomic particles in an atom: protons, neutrons, and electrons.
2. Understand that protons have a positive electric charge and are located in the nucleus of the atom.
3. Know that electrons have a negative electric charge and orbit the nucleus in electron clouds or shells.
4. Recognize that neutrons have no electric charge (they are neutral) and are located in the nucleus alongside protons.
5. Therefore, the subatomic particle with no electric charge and located in the nucleus is the neutron.
