Elements and compounds, accuracy and precision, liters and moles and joules—what does it all mean? After introducing the states, properties, and types of matter, this program proceeds to the periodic table of elements and the qualities of atoms, compounds, and molecules. An investigation of the metric system, SI units, uncertainty in measurement, and dimensional analysis wrap up this engaging educational resource. (26 minutes)

Atomic Structure
View Video Clip
Atomic structure lies at the crossroads of both chemistry and physics, and this program examines a field of study crucial to both: the scientific shell game known as quantum mechanics. Schrodinger's mathematical distribution and the Pauli Exclusion P...(more details)
 
Chemical Bonding

"An atom with eight electrons in its valence shell is a happy atom." Section one of this program makes sense of Lewis structures and resonance structures while addressing the Octet Rule and its exceptions. In section two, "Professor Einsteinium" and ...(more details)
 
Gases and States of Matter
View Video Clip
In part one of this program, chemistry authorities, including "Helium Man" and two janitors, lay down the law-Boyle's Law, Graham's Law, and Dalton's Law. They also present the Kinetic Molecular Theory and the Ideal Gas Equation and elaborate on part...(more details)
 
Moles, Percent Composition, and the Empirical Formula
View Video Clip
When is a mole not a mole? Section one of this program demystifies concepts such as Avogadro's Constant, molecular mass, and molar mass. In section two, the Percent Composition Formula is spotlighted, while section three addresses the Empirical Formu...(more details)
 
Chemical Equations and Atomic and Molecular Mass
View Video Clip
Can a barbershop quartet introduce the subject of stoichiometry? They do in this program, which in section one presents the Law of Conservation of Mass and how to balance equations. Section two explains the difference between the mass number and atom...(more details)
