Teacher Resources for Instructional Planning


Grade 8, Science Std 5.0: Differentiate between ionic and covalent bonds. • Illustrating transfer or sharing of electrons using electron dot diagrams • Identifying electron dot configuration of common elements (Periods 1, 2, & 3 only = Valence electrons). • Recognizing simple formulas. • Calculating the charge on ions.

Lesson Plans: Of Electron Bondage Students create models of ionic and covalent electronic bonds to demonstrate their understanding of these chemistry concepts. Ion (Derstand) Bonding through Energy Level Diagrams Determine the number of valence electrons using energy level diagrams. Solubility and Bonding I and II Students will identify a substance's bonding (ionic or covalent) from its chemical formula. Why Are Electrons Important? The student will be able to write the electron configuration of any element, given the atomic number. Given the location of an element on the periodic table, the student will be able to give the highest energy level the valence electrons are on, and how many valence electrons it has. Ionic Bonds Students will describe the characteristics of ionic bonds and state the octet rule. Atomic Structure and Ionic Bonding (A Visual Approach) Use the concept of the stable octet to predict simple molecular formulas.
