Which statement correctly defines a neutron in atomic structure?

• A. Electrons ejected from the nucleus.
• B. Protons ejected from the nucleus.
• C. Neutrons ejected from the nucleus of an atom.
• D. Gamma rays emitted by the nucleus.

Answer: (C)

A neutron is a neutral subatomic particle that resides in the nucleus of an atom along with protons. The statement that mentions neutrons in relation to the nucleus captures the essential idea of what a neutron is and where it is found. The other options describe electrons (which orbit outside the nucleus), protons (positively charged particles in the nucleus, not neutrons), or gamma rays (high-energy photons emitted by the nucleus, not particles). So the option focusing on neutrons in the nucleus best fits the concept of a neutron in atomic structure.
