Which type of nuclear emission has the greatest mass?

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

Answer: (B)

Verified step by step guidance

1. Understand the types of nuclear emissions: Gamma rays, alpha particles, beta particles, and neutrons are all forms of radiation emitted from unstable nuclei.
2. Recall that a gamma ray is a form of electromagnetic radiation and has no mass or charge.
3. Recognize that a beta particle is an electron or positron emitted from the nucleus, which has very small mass compared to nucleons.
4. Know that a neutron is a neutral particle found in the nucleus with a mass approximately equal to that of a proton.
5. Identify that an alpha particle consists of 2 protons and 2 neutrons, making it a helium nucleus with the greatest mass among the listed emissions.
