Organize these options into the right categories

Groups:

(a) Nuclear Fission (5)

,

(b) Nuclear Fusion (5)

• Uses uranium and other radioactive elements

• Two atoms join

• Naturally occuring on the sun

• Produces energy in stars

• Nuclear waste is an issue

• Atom is divided

• 1000 x stronger

• Chain reaction can occur

• Typically uses hydrogen and produces helium

• Used in nuclear power plants
