Which type of radiation has a physical mass like alpha radiation but has no electrical charge?

• A. Alpha
• B. Beta
• C. Gamma
• D. Neutron

Answer: (D)

Mass and electrical charge strongly influence how radiation behaves. The type described has real mass but no electric charge, which points to a neutron. A neutron is massive, like other nucleus-associated particles, but it carries no net charge, so it isn’t deflected by electric or magnetic fields. In contrast, alpha particles have mass and a positive charge, beta particles have mass and a charge (negative for electrons, positive for positrons), and gamma rays have neither mass nor charge. This combination of properties makes the neutron the correct choice.
