What is Radioactivityan the process by which an unstable nucleus gives of nuclear radiation What is given off durning an alpha decay and beta decay? energy
What is mass number the sum of the numbers of protons and neutrons in the nucleus of the atom. What is Nuclear Fission the combination of the nuclei of small atoms to form a longer nucleus releases energey
What is Isotopes an atom the same number of proton as other atom but has different numbers of neutrons Since gamma reay have light what does not have they have no mass or charge
What is half-life the needed time for half of a sample of a radioavtive substance What is Tracer is a radioactive element whose path be followed though a process of reaction
Hwn does a carbon -11 occur? when a proton breaks into a positron and a neutron what is the diiference do to masses and charge
since alpha particles are made up of 2 pront and2 neutron what do the have most of mass and charge of any type of decay what do beta particles start with electron or positrons,and have a1- it 1+ charge and almost no mass.
What nuclear chain reaction? a continous series of nuclear fissionreaction Who named the prrcess by nuclear readiation MArie curie was working with becquerel

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.

To see how well you know the information, try the Quiz or Test activity.
