Description
Atoms are composed of a central nucleus, containing positively-charged protons and neutrally-charged neutrons. Smaller, negatively-charged electrons travel around the nucleus in layered orbits called shells.

Description
Stoichiometry helps chemists find the relative amounts of reactants and products in chemical reactions. Balancing the number of atoms on each side of the equation, calculating the amount of each reactant, and figuring out which reactant will run out first are all fundamental principles when designing any chemical reaction. These principles are applied when splitting water into hydrogen and oxygen for energy, manufacturing sodium iodide for radiation...

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 partial pressures and the difference between diffusion and effusion. Part two investigates kinetic energy; ion-dipole, dipole-dipole, and London dispersion forces; hydrogen bonds; phase diagrams; and vapor...

This program traces the water cycle, beginning with the collection of rainwater in rivers and lakes, in great detail through a water treatment plant, to some of the places where water is used, and finally back into the atmosphere. Treatment of the water begins with the use of chlorine to destroy organisms; the water is then filtered through various sedimentation tanks to remove solid matter. Other treatments employ ozone, which oxidizes everything...

An explanation of how a mass spectrometer works is followed by a demonstration of a mass spectrometer in action. The analysis of simple mass spectra is discussed-simple splitting of hydrocarbons, the effect on splitting of heteroatoms in alcohols and ethers, and the McLafferty rearrangement. Discussion of the spectra of isotopic mixtures, such as chlorine and bromine, and the use of accurate masses is also included.

This Science Screen Report uses experiments and everyday phenomena to explore the properties of matter and how physical forces cause state changes at the boiling, melting, freezing, and dew point. The program also demonstrates how different states of matter can be combined in suspensions and solutions and how such mixtures can be separated into their components. Applied chemistry is spotlighted in the areas of food manufacturing and water desalination....
