Nuclear Chemistry

Which of the following best describes the process of nuclear fission?

• Splitting an atom's nucleus apart

• Splitting an atom's electrons in half

• Fusing two atomic nuclei together

• Separating an atom's electrons from its nucleus

In fission, a neutron is often used to start the reaction and it is also a product of the reaction. This is called a ____

• neutron emission

• nuclear fusion

• domino effect

• chain reaction
