Difference between the mass of an atom and the mass of its individual particles amu amu Mass Defect Nuclear Forces

Nuclear Binding Energy Energy released when a nucleus is formed from nucleons. High binding energy = stable nucleus. E = mc 2 E:energy (J) m:mass defect (kg) c:speed of light (3.00×10 8 m/s)

Nuclear Binding Energy Unstable nuclides are radioactive and undergo radioactive decay. The seven most widely recognized magic numbers as of 2007 are 2, 8, 20, 28, 50, 82, 126

Types of Radiation Alpha particle (  ) – helium nucleus paper 2+ Beta particle (  -) –electron 1- lead Positron (  +) –positron 1+ Gamma (  ) –high-energy photon 0 concrete ChargeShielding

Penetrating Ability of Radiation

Nuclear Decay Transmutation- One element becomes another. More than 83 protons means that the nuclei is unstable (radioactive)
