Nuclear Fusion and Nuclear Fission

The splitting of heavy nucleus into two lighter nuclei

• Nuclear Fusion

• Nuclear Fission

• Radioactive decay

• Beta decay

A Uranium-235 nucleus will split when it captures

• an electron

• an alpha particle

• a neutron

• a proton

Nuclear fusion is

• a loss of energy in nuclear reaction

• a loss of nucleon number and proton number in nuclear reaction

• the combining of two lighter nuclei to form a heavier nucleus

• the splitting of heavy nucleus into two lighter nuclei

Which statement describes nuclear fusion?

• Two hydrogen nuclei join to form a helium nucleus

• A helium nucleus joins with a hydrogen nucleus to form an alpha particle

• Uranium nuclei split and produce high energy neutrons causing a chain reaction

• Two helium nuclei join to form a hydrogen nucleus

Which of the following is not the similarity between nuclear fission and nuclear fusion?

• Both of the nuclear reactions experience mass defect

• Both of the nuclear reactions produced a large amount of energy

• Both of the nuclear reactions produced new nuclei

• Both of the nuclear reactions require very high temperature

In the Sun, energy is released when hydrogen nuclei collide and form heavier nuclei. This process is called ....

• ionisation

• diffusion

• fission

• fusion
