Alpha Emission
An Alpha Emission consist of two protons and two nuetrons. It is equivalent to a helium nucleus. The particles expel from the nucleus at approximately one tenth of the speed of light.





Beta Emission
A Beta Emission has a nuetron in the nucleus converted into a proton and an electron, then it ejects the electron. The remaining nucleus has one more proton than it has neutron, the atomic number increases and the mass stays the same.



Positron Emission
Positron Emission is like any other electron but it is positive. The proton goes to a nuetron and spits oput a positive charge.



Electron Capture
In a electon capture an electron in an atom's inner shell is drawn into the nucleus and combined with a proton. forming a nuetron and a nuetrino. The nuetrino is ejected. The atomic number decreases by 1 but the mass is constant.





Gamma Emission
A Gamma emission is a form of high energy electromagnetic radiation. It has no change in the atomic number or mass since it is a photon of light.





Conclusion
Alpha Emission - Two protons and two nuetrons and atomic mass is 4 & atomic number is 2

Beta Emission - Atomic number increase and mass stays the same.

Positron Emission - Positron is positive unlike other electrons and mass is 0 & atomic number is 1.

Electron Capture - Atomic number decrease by 1 and mass stays the same.

Gamma Emission - Gamma Emission is a photon of light and has no chnage in both the atomic number & mass.
