What happens when the number of protons in an atom changes? 

• The number of electrons always reduces to zero

• Usually nothing happens, unless the atom is radioactive 

• The atomic nucleus breaks down and decays

• It becomes a completely different atom, with different properties

This type of radiation has the highest penetrating power.  Even several inches thick of lead or several meters of concrete cannot stop all of it:

• Alpha

• Beta

• Gamma
