Fusion Quiz

Nuclear fusion occurs when

• Atoms collide and become one even though the protons have a negative charge

• Atoms Collide and become one even though the protons have a positive charge

• Atoms split despite the protons negative charge

• Atoms split despite the protons positive charge

In order for nuclear fusion to occur, what condition is required?

• It must be a liquid

• The molecules must move faster than the speed of light

• The molecules need to be excited by a significant amount of thermal energy

• All the above

Hydrogen is significant because...

• it is the first element on the periodic table

• the only element with one proton, but no neutron

• is the most abundant element in the universe

• All the above

In nuclear fusion, what happens when two atomic nuclei combine?

In a fusion reaction, what is the mass of the resulting nuclear compared to the total mass of the original nuclei?

• It is larger

• It is the same

• It is smaller

• It depends on the elements involved
