Unformatted text preview: s in nature gain stability by losing energy. •  Unstable nuclei lose energy by emiHng radia,on in a spontaneous process called radioac1ve decay. Types of Radia1on •  Alpha Radia1on (α) –  A par,cle containing 2 protons and 2 neutrons. –  Essen,ally the nucleus of a helium- 4 atom. –  Possesses a +2 charge. –  Used by Rutherford in the gold foil experiment. Beta Radia1on (β) •  Essen,ally a high energy electron spontaneously emiFed from the nucleus of the atom....
