Nuclear Fission Concepts and Reactions

The video tutorial explains nuclear fission, where a neutron accelerates towards a uranium nucleus, causing it to become unstable and split into smaller nuclei, releasing energy, gamma radiation, and more neutrons. This process initiates a chain reaction. According to Einstein's equation, the energy released, plus the mass of the smaller nuclei and neutrons, equals the original uranium nucleus mass, demonstrating mass-energy equivalence.

What happens to a uranium atom when a neutron is accelerated towards it?

• It releases all its electrons.

• It absorbs the neutron and becomes heavier.

• It becomes unstable and splits into smaller nuclei.

• It becomes stable and remains unchanged.

Which two elements are produced when a uranium nucleus splits during fission?

• Hydrogen and Helium

• Barium and Krypton

• Carbon and Oxygen

• Iron and Nickel

What is released along with energy during the chain reaction in nuclear fission?

• Gamma radiation and neutrons

• Beta particles

• Electrons

• Alpha particles

How does the chain reaction in nuclear fission continue?

• By stabilizing the nucleus

• By emitting more neutrons that cause further reactions

• By releasing more electrons

• By absorbing more protons

According to Einstein's equation, what is the relationship between the energy released and the mass of the uranium nucleus?

• Energy is more than the mass of the uranium nucleus.

• Energy is equal to the mass of the uranium nucleus times the speed of light squared.

• Energy is unrelated to mass.

• Energy is less than the mass of the uranium nucleus.
