Nuclear Fission vs Fusion

What is nuclear fission?

• It is the process by which stars generate light and heat

• Fission is the splitting of an atomic nucleus creating two smaller atomic nuclei

• Fission is the fusion of two atoms to create a heavier atom

• Fission is the process by which electrons are removed from an element

What must a nucleus absorb for fission to occur?

• Proton

• Electron

• Neutron

• Heat

Which of the following happens directly after or soon after an unstable isotope is initially hit with a neutron?

• The unstable isotope absorbs the neutron

• The unstable isotope breaks apart into smaller isotopes (fission products)

• Energy is released

• Neurons break off

What happens to the unstable isotope after it absorbs a neutron?

• The neutron is ejected (immediately leaves)

• It loses a proton

• It breaks apart into two smaller isotopes releasing more neutrons and energy

• It loses an electron

Which of the below are isotopes?

•
