Name the particle fired into an unstable nucleus to initiate fission

• Proton

• Alpha particle

• Neutron

• Electron

If a nucleus of U-235 absorbs a neutron, it becomes an unstable nucleus of:

• U-236

• U-234

• Pa-235

• Pa-236

The smaller, lighter nuclei formed during fission are called:

• Offspring nuclei

• Product nuclei

• Niece nuclei

• Daughter nuclei

Which of these are NOT a product of nuclear fission?

• Beta particles

• Neutrons

• Daughter nuclei

• Energy

Name the process shown in the image

• Alpha decay

• Nuclear fusion

• Binary fission

• Chain reaction

In a nuclear reactor, the rate of a chain reaction is decreased by:

• Decreasing the temperature of the fuel rods

• Adding more nuclear fuel

• Absorbing more neutrons

• Scattering more alpha particles

Which of these is NOT true about nuclear power stations

• Energy is released using nuclear fission

• The most common nuclear fuel used is Uranium

• They supply 20% of UK electricity

• They release greenhouse gases when they burn their fuel
