  • What three particles make up an atom?
    Protons, neutrons, and electrons.
  • What happens during fusion?
    Atoms combine to form a new atom and release energy.
  • What two elements combine in the Sun during fusion?
    Hydrogen atoms combine to make helium.
  • Where is uranium found?
    Uranium is found in rocks in the ground.
  • Why is uranium called nonrenewable?
    Because we cannot make more uranium.
  • Why is nuclear power considered clean?
    Because it does not burn fuel that pollutes the air.
  • What is radiation?
    Radiation is energy released in the form of rays.
  • What happens during fission?
    One atom splits into two smaller atoms and releases energy.
  • What type of energy is released during fission?
    Heat and radiation are released.
  • What is the energy inside the nucleus called?
    It is called nuclear energy.
  • What are atoms?
    Atoms are tiny particles that make up everything.
  • What is the center of an atom called?
    The center of an atom is called the nucleus.
  • How many protons does oxygen have?
    Oxygen has eight protons.
  • How many protons does uranium have?
    Uranium has 92 protons.
  • How is radiation helpful in medicine?
    Doctors use x-rays to take pictures of bones and teeth.
  • How is heat from fission used?
    It is used to produce electricity.
  • Where can radiation come from?
    It can come from the sun, older TV sets, and food.
  • What determines what kind of atom it is?
    The number of protons determines the type of atom.
  • Why do some people worry about nuclear energy?
    Because radiation can be dangerous and used fuel remains radioactive.
  • How many different atoms have been found so far?
    118 different atoms have been found.
