Question

How is the nucleus of an atom split?

radioactive decay
chemical reaction
collision of atoms
collision with a high-speed particle

Answer 1

D. Collision with a high-speed particle.

Step-by-step explanation:

During a process called nuclear fission, some nuclei can be hit by fast-moving atomic particles and thus can be broken down into smaller nuclei. Energy is given off in this process, which is the basis for nuclear power plants.

Answer 2

Collision with a high-speed particle
