Teacher Resources for Instructional Planning


Grade 8, Science Std 3.2: Identify the first 3 levels of the electron cloud configuration and state how many electrons can fit in each level. • Describing how the atomic number and mass number determines the amount of subatomic particles. • Interpreting a Bohr diagram

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. Confirming and Visualizing Lewis Dot Structures With this activity, students can calculate and visualize the atomic and molecular structures of bonds. The Numbers Game Find the atomic number, mass number, proton number, neutron number, and electron number. The Element Project These models will demonstrate their ability to visualize the Bohr model of the atom and how the protons, neutrons, and electrons are situated in the model. Ion (Derstand) Bonding through Energy Level Diagrams Determine the number of valence electrons using energy level diagrams.

Resources: Great Periodic Table Resource Electron configurations for all elements Chemical Bonding Good explanations and examples of chemical bonding Chem4kids Great tutorials and activities Chemistry Experiments Lots of great demos and labs
