chapter 7 radiation

B.C. science 10

Alpha particle a positively charged atomic particle that is much more massive than either a beta or gamma radiation
beta particle high speed negatively charged electron emmited by a radioactive nucleus in beta decay
gamma particle rays of high energy, short wave radiation emitted from nuclei of atoms
isotopes different atoms of a particular element that have the same number of protons but different number of neutrons ( different atomic mass )
light one form of radiation that is visible to humans
mass number the total number of protons and neutrons found in the nucleus of a atom
radiation as high energy rays and particles emitted by radioactive sources
radioactivity release of high energy particles and rays of energy from a substance as a result of changes in the nuclei
proton a sub-atomic particle that has a positive electric charge ( 1+ )
neutron a sub-atomic particle that does not have a electric charge
electron a sub-atomic particle that has a negative electric charge ( 1- )
nucleus the mass of the atom made up of protons ( 1+ ) neutrons ( neutral )
radioactive source a source of radiation
Ernest Rutherford A canadian chemist who received a nobel prize for research into chemistry into radioactive substances.
Alpha decay emission of a alpha particle ( 1- ) from a nucleus
beta decay a neutron changes into a proton ( 1+ ) that stays in the nucleus, and a electron ( 1- ) that shoots out from the neucleus with lots of engergy
gamma decay results from a redistribution of energy within the nucleus giving off a high energy gamma ray as the isotope falls from a high energy state to a low energy state
nuclear equation a set of symbols that indicates changes in the nuclei of atoms during a nuclear reaction
Radio isotopes natural or man-made isotopes that decay into other isotopes relasing radiation

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.
