Lesson Plan: Electronegativity Chemistry
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to explain the chemical property of electronegativity.
Objectives
Students will be able to
- define and understand the concept of electronegativity,
- describe trends in electronegativity across the periodic table,
- use Linus Pauling’s numerical values to compare the electronegativity of different elements,
- list factors that affect electronegativity,
- predict the type of bonding that is likely to occur from differences in electronegativity.
Prerequisites
Students should already be familiar with
- the basic concept of intermolecular forces,
- ionic and covalent bonding,
- the concept of electron shells and simple electronic configuration,
- the calculation of electronegativities using bond dissociation energies.
Exclusions
Students will not cover
- polar bonding or polar molecules in detail,
- how electronegativity relates to polar and nonpolar solvents,
- other scales used to measure electronegativity.
