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

Integrated Science Mr. Danckers Chapter 10.
Radioactivity and Nuclear Reactions PS-2.2: illustrate the fact that the elements exist as stable or unstable isotopes PS-2.6: compare fission and fusion.
QUIZ NUCLEAR CHEMISTRY. NUCLEAR CHEMISTRY QUIZ 1.Compare what happens to atoms in both a chemical reaction and a nuclear reaction. 2.What happens to the.
What is it to be Radioactive? Radioactive decay is the process in which an unstable atomic nucleus loses energy by emitting radiation in the form of particles.
NUCLEAR CHANGES What is Radioactivity?. What happens when an element undergoes radioactive decay? During radioactive decay an unstable nuclei of an isotope.
Nuclear Decay. Radioactivity The emission of high-energy radiation or particles from the nucleus of a radioactive atom.
Nuclear Chemistry. The Atom The atom consists of two parts: 1. The nucleus which contains: 2. Orbiting electrons. protons neutrons.
Nuclear Radiation Half-Life. What is Radiation? Penetrating rays and particles emitted by a radioactive source Result of a nuclear reaction! –Involves.
Radiation Radiation: The process of emitting energy in the form of waves or particles. Where does radiation come from? Radiation is generally produced.
