Atomic Energy

QuestionAnswer
Who discovered radioactivity? Henri Becquerel
What type of energy is emitted by radioactive decay? Nuclear Radiation
What are the 3 types of radioactive decay? Alpha decay, Beta decay, and Gamma decay.
Alpha decay releases alpha particles. What are alpha particles? An positively charged particle, made up of 2 protons and 2 neutrons. (Helium)
What is conserved after radioactive decay? Mass and Charge.
What is beta decay? The process of of a neutron breaking down into a proton and electron;the electron being released.
What are gamma rays? Pure energy released by gammaa decay. They do not have mass or charge, so they cannot change an element.
Name some examples of radioactive damage on matter. Weakend structures, radiation sickeness, and Death.
What are the penetrating power of the 3 radioactive decays? Alpha particles can be stopped by paper. Beta particles can be stopped by aluminum. Gamma rays can be stopped by a few meters of concrete or a few centimeters of lead.
Define half- life. The extent for half of an radioactive substance to decay.
Uses of Radioactivity. X-rays, tracers, and a source of energy.
What is nuclear fission? The dividing of an atom's nucleus; releasing energy, and extra neutrons.
Advantages of nuclear fission. Huge amounts of energy is gained, no pollution, and less expenses to run a nuclear power plant.
Diadvantages of Nuclear Fission. Creates hazardous, radioactive materials, that's not gonna go away in just a few days.
What is Nuclear Fusion. The combination of the nuclei of small atoms to form a larger nucleus; thus releasing energy.
Advantages of Nuclear Fusion. Creates very little amounts of radioactive waste, and their is potential of vast amounts of energy, form hydrogen isotopes.
Problem with Nuclear Fusion. It takes a great amount of heat, for nuclear fusion to work. (100,000,000/C) So it is not possible for now.
Who named the process of radioactive decay? Nobel prize

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
