Answer the following question given this paragraph: The use of nuclear fusion for energy has several pros. Unlike nuclear fission, which involves dangerous radioisotopes, nuclear fusion involves hydrogen and helium. These elements are harmless. Hydrogen is also very plentiful. There is a huge amount of hydrogen in ocean water. The hydrogen in just a gallon of water could produce as much energy by nuclear fusion as burning 1,140 liters (300 gallons) of gasoline! The hydrogen in the oceans would generate enough energy to supply all the world's people for a very long time. Q: Unlike nuclear fission, which involves dangerous radioisotopes, nuclear fusion involves what two harmless elements? Choices: - magnesium and helium - hydrogen and oxygen - hydrogen and carbon - hydrogen and helium A:
(Answer)
hydrogen and helium

Answer the following question given this paragraph: A proton is a particle in the nucleus of an atom that has a positive electric charge. All protons are identical. It is the number of protons that gives atoms of different elements their unique properties. Atoms of each type of element have a characteristic number of protons. For example, each atom of carbon has six protons, as you can see in Figure below . No two elements have atoms with the same number of protons. Q: Which particle of an atom has a positive electric charge? Choices: - electron - nutron - nucleus - proton A:
(Answer)
proton
