Chemistry 5-11-09 Fission and Fusion
Can you believe it! Here’s the last lecture from Chemistry 08-09! Just a brief overview of fission and fusion.
Good luck studying for the laaaaaaaaaast chapter test of the year! I’ll be praying for you!! Did you think the day would ever come! Be careful and don’t take the test for granted. Make sure you practice half-life problems and nuclear equations. Also, make sure you’ve memorize the nuclear symbols for alpha particles, beta particles, positrons, neutrons, and protons. And then there are tons of notes on the conceptual stuff. Properties of radioactivity, people, types of radioactive decay, applications of radioactivity, definitions, definitions, and definitions! Practice! And did I mention, PRACTICE!!

As far as Beta goes, us paper rollers the onlu use?

trey,
nuclear fission is when a very heavy nucleus splits into more-stable nuclei of intermediate mass.

Are Gamma Rays the biggest or the strongest or both?

Hey Tim Morris, the gamma rays are the strongest in penetration.

which one of the types of radiation penetrates the farthest??

JD,
gamma radiation is the farthest penetrating

Which one of the types of radiation penetrates the least?
[Reply]
May 12th, 2009 at 8:44 PM
Robin: The least penetrating radiation is alpha. It is only strong enough to go through paper.

WHat are control rodsd used for in a nuclear reactor?

Jalen control rods are u se to aborb neutrons to helo control the reaction. This limits the number of free neutrons.

What is the moderator and coolant used for?

Jalen: control rods keep the reaction from getting out of control

what is the difference between fussion and fission?
[Reply]
May 13th, 2009 at 10:32 AM
fission is the splitting of an atom and fusion is combing of the nuclei, yeah elizabeth your welcome

Ashley-
Fission is the splitting of an atom into two parts.

to much radiation can cause cancer, which is pretty much why it is so harmful.

what did the moderator do on that test

May 13th, 2009 at 9:37 PM
Mrs.Skinner, on the test what was the cooling system of the power plant?

Really informative and self explaining post.Your posts prompt others explore further deeper.

I am still totally confused on the difference between fission and fusion! So what is the difference?
[Reply]

Marissa…
Fission is splitting an atom but fusion combines them
[Reply]
May 14th, 2009 at 9:45 PM
well… it’s finally coming to an end… and we had to leave off on nuclear stuff to… now I’m gona wind up blowing something up over the summer
