Explain and compare nucluear reactions ( radioactive decay,fission and fusion), the energy changes associated with<br />
them and their asscociated safety issues.<br />
Notes Section:<br />
lpha looks like the nuclues of a heluim particle. Becaus they both have 2 protons and two nuetrons<br />
aughter is what we eject the aftter alpha particle. It pushes the nuclues 2 meters in air due to the<br />
eason it doesnt have Enough energy. It ejects because it is trying to become a stable atom,<br />
hanges becasue of the condition of the nuclues. We use the periodic table to determine the new<br />
thing which woulld have two less.Polumiom will give off two and become lead to beacome stable. It<br />
s not necasary to get stable only accurs sometimes.<br />
eta have the mass of electron it has very small amount of mass.It is negative. We wil take give<br />
wyay aelectrons so it becomes a proton . Its basically another way to make it nueatral. Cannot cau<br />
oves little further then beta.The betta goes up by 1.<br />
or example<br />
ranium becomes neptium becuse uranium adds one to become NP.<br />
roton give its postive charge to become nuertral. It makes it less table which makes it transform.<br />
Beta particles decay<br />
e+<br />
IN this situation the proton gives off it postive charge by going up one because the postive gives<br />
away to become nuetral.<br />
WHile E- it goes down 1<br />
Gamma radiation has to go through a transformation such as alpha particle decay or beta decay<br />
cause gamma radiation but slighty sometimes it does not<br />
Half life;<br />
After two days you would have half the mass due to the fact that it goes through a two day procce<br />
