Chapter 25 Notes!!! Enjoy! Have fun!   Read like a pig!  Oink like a dog!  Bark like a cow!  Moo like a hawk!  Try to be sane (but inane!)!
The Players     a         b           g       Proton        or      Neutron  Positron See Figure 25.1		Know a , b , and g decay. These occur naturally in elements above 83.     RATIO     If is TOO LARGE If is TOO LOW

Know p. 882 a , b , g

Know INDUCED RADIOACTIVITY
That's strange...I think I'm beginning to glow...hmm....glow?  Yes, glow... yes.... right... glow...

1. Neutron Bombardment
2. K-Electron Capture
2. 

Elements above 94 are man-made by neutron bombardment or or others.

Score...can you read this?  Isn't it amazing?  I'm writing in GREEK!  SCORE SCORE SCORE!!!  What?  you can't understand what I'm trying to say?  Oh, poor, you.  ANYWAY...here is nuclear decay!  Have fun!  AND READ!

PROBLEM:
Problems...I used to have a problem.  I think I still do.  That could be a problem.  Right?  What am I doing?  ARGH!  I feel like a dork.  HEY HEY!  YA.  Random inane comments.  Yes.  INANE.  Not insane.  INANE.  And how are you doing today?

The half life of Mareksteinium is 39.2 years. If you have 75.2 g of it, how much will be left in 100. years?

GIVEN:     m = 75.2 g       t = 100. years
=  39.2 years
FIND: amount left

Use . So we need to calculate:
                                               m = and x = amount left
We also need k:

    

See p. 900: Reaction 25.22, 25.23, 25.24

Fission...here's what MY definition of fission is: When fission occurs, you ...oh doh.  There goes the bell.  I must leave now.  OKAY.  BYE!

FISSION: Be able to recognize it ® the splitting of a heavy isotope by bombardment with a neutron into 2 middle weight isotopes and more neutrons + energy

(also energy)

(see other OH’s)
see OH - 6

FUSION: The joining of light nuclei to form heavy ones with the release of ENERGY

You have to have very high temperatures (100 m° ). You have the PLASMA STATE where "e" are ripped off. Ninety-nine percent of matter in the universe is this.

In both FUSION and FISSION small amounts of mass are LOST (products < reactants) - it goes into energy via:

If I had a donkey and a cow...I could make a cowkey!
