Transform two-dimensional electron dot diagrams into three-dimensional electron models with this hands-on kit. -- After studying electron dot diagrams to understand bonding in covalent molecules, students apply their knowledge and build a three-dimensional covalent molecule model that illustrates molecular structure. -- Concepts covered include molecular geometry, single, double and triple bonds, the octet rule, and polarity of bonds and molecules. The lab can be completed in 40 minutes. -- Includes: 10 complete molecular model packets with bonding tubes and carbon, hydrogen, oxygen and chlorine atom models; and complete instructions featuring a teacher’s guide with answers, and a reproducible student guide with background information, step-by-step procedures and hand-in worksheets. |
