UNC Chemistry Fundamentals An Interactive Educational Exercise Because of special formatting tags needed to display exponents, this site is best viewed with Netscape 3.0 or higher. If needed, use the link under Useful Materials to download Netscape About the Chemistry Fundamentals Course This exercise is designed for anyone who wants an introduction or review of the fundamentals of chemistry that will be used in freshman level chemistry classes. This interactive course was used for the first time during the summer of 1997. Evaluations from last year's materials suggested that, while the mathematics and calculator sections were useful, one of the most appreciated benefits of the materials was the review of basic high school chemistry. Currently, this site is used as a resource that can be beneficial to any student that is enrolled in a freshman chemistry course. About these materials How to use these materials The basic procedure is as follows:Take the pre-test for a certain sections. About the Sidebar

Chemistry | 5.112 Principles of Chemical Science, Fall 2005 | Video Lectures | Lecture 26: Molecular Orbital Theory ChemTube3D Types of Bonds Custom Search Bonding Links <-- Back to electronegativity Electronegativity Differences between atoms can be used to determine the type of bonding that occurs. If the difference between 2 atoms is small (less than 1.7) the bond is covalent. If the difference is large (greater than 1.7) the bond is considered ionic. Exceptions- HF is covalent not ionic (difference of 1.9) BF3 is covalent (difference of 2.0) BeF2 is covalent (difference of 2.5) Covalently bonded atoms will share their electrons in order to form a stable outer electron shell that has 8 electrons. This is called an octet of electrons. Ionic is 1 minute in. Ionic bonded atoms will transfer one or more electrons from the less electronegative element (a metal) to the more electronegative element (a nonmetal) as to achieve an octect of electrons. This results in the formation of 2 ions. The bond is a strong electrostatic attraction formed by 2 opposing ions. Chemical Demonstration Videos

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. They are intended only as practice of concepts and vocabulary that are essential to your success in this course. Each time you reload the activity, the problems will be in a different order, and the answers will be reshuffled!

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. The model-based activities are presented in a variety of sizes, styles, and degrees of teacher support, but a subset of Stepping Stones (See Overview of Stepping Stones) has been built to provide entries to larger domains. colored icons to indicate degree of support technological requirements links to concepts and disciplines links to standards links to some textbooks Activities can be accessed by typing an activity number in the field Jump to Activity at top right. Note: This database is in development.
