If the difference between 2 atoms is small (less than 1.7) the bond is covalent. AP Chemistry Review Activities AP Chemistry Interactive Review Activities In keeping with the new framework for AP Chemistry beginning in 2013 - 2014, I am indicating here if the topic to which a review activity relates has been dropped from the curriculum. It will be identified as excluded (Excluded) to indicate that the College Board has specifically excluded it. I will leave the reviews here, however, in case some of you find them useful. These are not graded assignments.
MOLO - Database The Molecular Logic Database is designed to provide teachers and students with easy access to our model-based activities. The activities are derived largely, but not entirely, from projects of the Concord Consortium sponsored by the National Science Foundation (NSF). The models are primarily of interactions of atoms and molecules, or rule-based genetics.
Chemistry Central blog We are pleased to announce that Professor Liang-Nian He, a Professor of Chemistry at the State Key Laboratory of Elemento-Organic Chemistry, Nankai University, China has joined the Editorial Board for Sustainable Chemical Processes. His research interests include: green synthetic chemistry; synthesis and application of task-specific ionic liquids; catalysis in green solvents such as ionic liquids, PEG and water; CO2 chemistry; biomass conversion, particularly chemical transformations of CO2 into fuels, chemicals and materials; and CO2 capture and utilization. Associate Professor Michael Oelgemöller from James Cook University, Australia also joins us on the Editorial Board. Chemical Bonds Selected by the SciLinks program, a service of National Science Teachers Association. Copyright 2001. For an explanation of the significance of this logo go to: Because of the tendency of atoms to complete their outer energy shells with the stable number of electrons for each shell, atoms with incomplete shells have a tendency to gain electrons, lose electrons or share electrons. Atoms that have gained or lost electrons become ions. Oppositely charged ions form ionic bonds.
chemistry - dawnwelch7 Introductory Activity Rubric Matter and Its Changes Separating Mixtures Lab Information Packet chemsoc timeline - flash We would like to invite you to suggest other items for inclusion in the chemsoc timeline. All genuine suggestions will be considered and those accepted will be credited to the individual responsible! The events do not have to be chemistry related - just notable discoveries or incidences that are of interest to scientists and the general public. Please Email email@example.com with your suggestion, where possible please include the date the event/discovery took place and some basic details: where it took place, who was involved and maybe some other sources of information. You can even make predictions for inventions or discoveries that you think will be made in years to come. For example if you think teleportation will be possible in 2020, why not suggest it to us!
