Lesson Plan: Electronegativity Chemistry • Second Year of Secondary School
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.
