Nuclear Chemistry
Nuclear Chemistry
Nuclear Reaction Anytime the nucleus of an
atom changes.
2
Types of Nuclear Reactions
Fission
Fusion
Radioactive Decay
3
Fission
The splitting apart of a large atom (nucleus)
into two smaller atoms
4
Fusion
The combining of two small atoms to produce a
single larger atom
5
So Whats the Point?
The products of a fission and a fusion reaction
weigh less than the reactants.
In other words, matter disappears!
Where does the matter go?
It turns into energy! According to the
equation E mc2
The point is You get a poop load of energy!

Chain Reaction

Fission
The splitting apart of a large atom (nucleus)
into two smaller atoms

Critical Mass
When a hunk of fissionable material can keep
reacting on its own

The Nagasaki Bomb - Compared to the one used on
Hiroshima, the Nagasaki bomb was rounder and
fatter. It was called "Fat Man." The material
used was plutonium 239. The fission of slightly
more than one kilogram of plutonium 239 is
thought to have released destructive energy
equivalent to about 21,000 tons of TNT.
The Hiroshima Bomb - Due to its long, thin shape,
the Hiroshima bomb was called ³Little Boy². The
material used was uranium 235. It is believed
that the fission of slightly less than one
kilogram of uranium 235 released energy
equivalent to approximately 15,000 tons of TNT

Radioactive Decay
11
Why are some atoms radioactive?
1) They dont have the proper ratio of protons
to neutrons or 2) They are too stinkin
big
