How it works.
What do you need to know about Nuclear Chemistry?
- Radioactivity-Radiation resulting from radioactive decay.
- Half-Life-The half-life is the amount of time it takes for half of the atoms in a sample to decay.*(N=No(1/2)^n)
*N=the remaining amount
No=the initial amount
n=the number of half-lives that have passed.
- Fusion-The process of binding smaller atomic nuclei into a single,larger, more stable nucleus.(i.e, the sun)
- Fission-the splitting of nucleus into a smaller more stable fragments with a large release of energy.(i.e nuclear power plants)
Types of radioactive decay
Beta- a beta particle is a high energy electron; it has more energy than an alpha particle. a beta particle.A beta particle can be stopped by aluminum foil.There are three types of beta decay:
- Regular beta
- Reverse beta
- Electron beta
Gamma- Gamma rays are high energy x-rays.They can be stopped by led.Gamma rays have a lot of energy and are very harmful to living cells.
