**It's best to visit us on the web at General Chemistry Lecture Notes


General Chemistry Lecture Notes -- for a typical nineteenth chapter ("section") of a high school chemistry course (AP, honors, regular) -or- college-level general chemistry course.

Excellent for instructors who like to write out their lecture notes on the board "as they teach"...


19-1 -- The Nucleus

· Protons and Neutrons

· The Relative Size and Density of the Nucleus

· The Energies Associated with Nuclear Reactions

19-2 -- Some Nuclear Definitions

· Nucleons

· Atomic Number (Z) and Mass Number (A)

· Isotopes and Nuclides

19-2 -- Nuclear Stability and Radioactive Decay

· A Typical Radioactive Decay Process

19-3 -- Types of Radioactive Decay Reactions

· Alpha-Particle Production (a-particles)

· Spontaneous Fission

· Beta-Particle Production (b-particles)

· Gamma Ray Production (g-rays: photons)

· Electron Capture

· Positron Production (b+-particles)

19-5 -- Writing and Balancing Nuclear Reactions

19-5 -- Radioactive Decay Series

19-6 -- Half-Life (t½)

· Half-lives of Radioactive Nuclides

· First-Order Decay Processes

19-6 -- Detection of Radioactivity
