Nuclear Chemistry Mr. Skirbst Physical Science Topic 21

Nuclear Chemistry Radioactivity -

Nuclear Chemistry Radioactivity – - a release of matter and energy that changes the nucleus of an atom

3 Types of Radiation 1. Alpha particles

3 Types of Radiation 1. Alpha particles (+) 2 protons & 2 neutrons - can burn skin, but is stopped by paper

3 Types of Radiation 2. Beta particles

3 Types of Radiation 2. Beta particles (-) 1 electron & (+) 1 proton (from neutron decay) - can penetrate 3 mm of Al

3 Types of Radiation 3. Gamma Rays

3 Types of Radiation 3. Gamma Rays an electromagnetic wave (no charge) - penetrates several centimeters of Pb (lead)

3 Types of Radiation TypeAt. MassCharge

Nuclear Stability Describes the “strength” of the nucleus

Nuclear Stability Binding Energy - nuclear force that holds the nucleus together

Nuclear Stability Radioactive Decay - unstable nucleus breaks down & releases energy & matter

Nuclear Stability 2 Types of Decay: Alpha decay -releases (2P & 2N) Beta decay - releases (1E & 1P from 1N)

Nuclear Stability Decay typeat. Massat. # -4-2 same+1

Nuclear Stability Half Life: - time it takes for ½ the atoms to decay

Nuclear Stability Nuclear Notation:

Nuclear Stability Decay Series: - Illustrates radioactive decay

Nuclear Energy Fission – splitting of atomic nucleus

Nuclear Energy Fusion – combining of atomic nucleus
