Chemistry: Naming Cations & Understanding Nomenclature


www.mindbites.com Naming chemical compounds can be tricky, and requires a little bit of knowledge about the trends and naming conventions. First, Professor Harman explains that how you name a compound will depend on the type of compound – whether it is an ion, molecular compound, acid, or base. For ions, the way you name the ion will depend on whether the compound is a cation or anion and whether or not it is monatomic, polyatomic, or a transition metal. Anions follow slightly more difficult naming conventions. Molecular compounds use Greek prefixes and will always start with the element furthest from Fluorine. Some molecular compounds have common names (such as water), and these are always used. Bases are simply named like ionic materials. Acids are named based on the suffix of the anion they are derived from. If the anion ends in -ate, the acid uses an -ic suffix. If the anion ends in -ite, the acid uses an -ous suffix. Taught by Professor Harman, this lesson was selected from a broader, comprehensive course, Chemistry. This course and others are available from Thinkwell, Inc. The full course can be found at www.thinkwell.com The full course covers atoms, molecules and ions, stoichiometry, reactions in aqueous solutions, gases, thermochemistry, Modern Atomic Theory, electron configurations, periodicity, chemical bonding, molecular geometry, bonding theory, oxidation-reduction reactions, condensed phases, solution properties, kinetics, acids and bases, organic reactions

Dr. McCord on “What is QA?”


Dr. Kerry McCord is a graduate of Logan College of Chiropractic and a Diplomate of the International Board of Applied Kinesiology. As a practicing chiropractic physician since 1973, Dr. McCord has served on Committees of the ICAK, as Chair and Co-Chair, and written 14 papers for presentation at its annual meetings. In 2002, he began collaborating with Walter Schmitt, DC, DIBAK, DACBN, and teaching the body of work now known as QUINTESSENTIAL APPLICATIONS (QA). Dr. McCord was the catalyst for the production of the QA Book (co-authored with Dr. Schmitt), Audio (ICAK paper discussing the QA thought process) and Course (www.quintessentialapplications.com), and is co-owner and clinical director of HEALTHWORKS!, a healthcare delivery and health education company specializing in motivational wellness. Dr. McCord has lectured nationally and internationally on stress, stress-induced illness and Applied Kinesiology. Dr.Walter H. Schmitt is a graduate of Duke University (1970) and the National College of Chiropractic (1974) and practices in Chapel Hill, North Carolina. He was the first doctor to hold diplomate status in both applied kinesiology and chiropractic neurology. Dr. Schmitt is the author of two books for professionals, Common Glandular Dysfunctions in the General Practice (1981) and Compiled Notes on Clinical Nutritional Products (second edition, 1990) and one book for the public, Stop Your Pain Now! (2000). With Dr. Kerry McCord, he is the coauthor of QUINTESSENTIAL
