week of February 22nd

We have started our unit on atomic energy and have read through chapter four, section one. Expect a quiz on this material on Friday--unless of course we get more snow.

Topics to review include the definition of nuclear radiation, the concept of radioactive decay and atomic mass. Be able to compare and contrast alpha, beta and gamma decay. Think about both particle size and penetration.

We did discuss half-life in class today--It will not be on friday's quiz but it would be a good idea to review the concept.
