A neutron particle is characterized by which of the following?

• A. Positively charged
• B. Neutral
• C. Positively charged and heavy
• D. Negatively charged

Answer: (B)

Neutrons are electrically neutral. They have no net electric charge, unlike protons which are positively charged and electrons which are negatively charged. This neutrality means neutrons don’t interact with electric or magnetic fields in the same way as charged particles, and they don’t produce ionization directly as they travel. Instead, they interact mainly through the strong nuclear force when they collide with nuclei, which is why shielding and detection rely on nuclear interactions and secondary charged products rather than simple Coulomb interactions. The neutron’s mass is similar to that of the proton, so it contributes significantly to nuclear mass without carrying a charge.
