Answer:
Neutron (¹₀n)
Step-by-step explanation:
Nuclear Fission: This is a process in which two or more light nuclei fuse or combine to form a heavier nucleus with a release of energy and radiation.
Neutron: A neutron is located in the nucleus of an atom, It has a neutral charge, The mass of neutron is 1.660540 x 10⁻²⁷ kg
Therefore The type of radiation emitted during a nuclear process in which a nucleus with greater atomic number is formed is Neutron (¹₀n)
