__Alpha Emission:__
__ http://lhs.lps.org/staff/sputnam/chem_notes/alpha.gif____ Alpha emission is when a nucleus emits a particle that has 2 protons and protons bonded together that changes into an atom that has the mass number with four less and then atomic mass number of 2 less.

The equation to represent this is: 210 over 84PO>206 over 82PB+4 over 2HE

=__Beta Emission:__= __ http://lhs.lps.org/staff/sputnam/chem_notes/alpha.gif Beta emission is when radioactive decay occurs and the electron is emitted from the nucleus as a beta particle. The equation to represent this is:

_ =Positron Emission:= []__|http://physics.unco.edu/sung/sci103/nuclear/positron_decay.gif[|]__]] Positron Emission is when a particle has the same mass as the electron and is emitted from the nucleus of the atom.

The equation to represent this is__:__

=Electron Capture:= http://universe-review.ca/I08-26-nstar1.jpg Electron Capture is when an electron is captured by a nucleus during radioactive decay. The equation to represent this is: 0/-1e+1/1P->1/0n _

=Gamma Emission:= http://www.islamicmedicine.org/medmiraclesofquran/rays.gif Gamma Emission is when a nucleus emitts high-energy photon when it changes from excited state to low energy state.

The equation to represent this is: http://www.shodor.org/unchem/advanced/nuc/ _

=Conclusions:= Alpha Emission: a positively charged atom that is released during radioactivity that consists of two protons and two neutrons. Beta Emission: an electron that is emitted during radioactive decay. Positron Emission: a particle that has the same mass as the electron that is emitted from the nucleus. Electron Capture: an electron is captured by the nucleus during radioactive decay. Gamma Emission: when a nucleus emitts high-energy photon when it changes from states. __
