  2. Outline • Slide 1- Cover Slide • Slide 2- Outline • Slide 3- Alpha Emission • Slide 4- Beta Emission • Slide 5- Positron Emission • Slide 6- Electron Capture • Slide 7- Gamma Emission • Slide 8- Conclusions • Slide 9- Bibliography

  3. Alpha Emission In Alpha Emission both the number of neutrons and number of protons need to be reduced in order to increase stability of the nucleus. 210PO  206 Pb+ 4 He 84 82 2

  4. Beta Emission A Beta Emission is a type of radioactive decay in which a neutron is converted to a proton with the emission of a beta particle. 14C  14N + 0B 6 7 -1

  5. Positron Emission A Positron Emission is when having to decrease the number of protons, a proton can be converted in to a neutron by emitting a positron. 38K 38Ar + 0B 19 18 +1

  6. Electron Capture An electron capture, an inner orbital electron is captured by the nucleus of its own atom. 106Ag+0e106Pd 47 -1 46

  7. Gamma Emission Gamma Emission usually occurs directly after other types of decay, when other types of decay leave the nucleus in an excited state.

  8. Conclusion All these emissions are forms of decay. It states how quickly something will fade away. In most of the processes of decay the number of one of the particles in the atom will be reduced.
