Question

Uranium-238 decays into Thorium-232 by emitting

Answer 1

Answer:

D alpha particles

Explanation:

Radioactive U-238 will decay into Thorium -232 by emitting alpha particles in the process of nuclear fission.

Nuclear fission is the radioactive decay process in which a heavy nucleus spontaneously disintegrates into two lighter ones and several other particles with a large release of energy.

     U-238      →     Th-232 + alpha particles +  2 neutrons + energy

This way the mass and atomic numbers are conserved;
