Lesson Plan: Valence Science • First Year of Preparatory School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to determine the valence of different elements.
Objectives
Students will be able to
- recall how the number of electrons in the outer shell of an atom affects chemical reactions,
- explain how atoms complete their outer shells of electrons during chemical reactions,
- define the term valence,
- use electronic configurations of atoms to deduce their valences,
- highlight elements that have multiple valences,
- give examples of polyatomic ions and their valences.
Prerequisites
Students should already be familiar with
- electronic structure.
Exclusions
Students will not cover
- deduction of a chemical formula.
