Teacher Resources for Instructional Planning


HS, Physical Science Std 3: Contrast the formation of ionic and covalent bonds based on the transfer or sharing of valence electrons. • Demonstrating the formation of positive and negative monatomic ions by using electron dot diagrams • Define role of electrons in chemical reactions and bonding

Lesson Plans: 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. Comparing Ionic and Polar Covalent Crystals Students will be able to discuss the similarities between ice crystals and ionic crystals using qualitative observations and drawings. 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. Binary Ionic Compounds Can you write formulas for binary ionic compounds? Can you name binary ionic compounds? Let's find out... Polyatomic Ionic Compounds Identify the formula and name of each of these ionic compounds that use polyatomic ions. Diatomic Molecules These molecules are composed of two atoms of the same element.

Resources: "Happy Atoms." Good Tutorial Chem4kids Great tutorials and activities. Tom Stretton's Chemistry Pages Great tutorials and practice problems The Periodic Table of Comic Books Associates each element with a comic reference - fun Interactive Periodic Table Created by an eighth-grade student!
