Lesson Plan: Noble Gases Chemistry • 7th Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to compare the physical properties of noble gases and explain their inertness in terms of electron-shell filling.
Objectives
Students will be able to
- identify the position of the noble gases (group 18) on the periodic table,
- name the elements of the noble gases,
- state and use the electronic configuration of group 18 elements to explain why these elements are unreactive monatomic gases,
- describe and explain the pattern in the physical properties of the noble gases,
- recall the intermolecular forces that exist between atoms in order to explain the trend of boiling points as we move down the group,
- give some applications of noble gases and relate these uses to their physical and chemical properties.
Prerequisites
Students should already be familiar with
- simple electronic configuration and shell diagrams,
- changes of state explained through the particle model.
Exclusions
Students will not cover
- van der Waals forces or dispersion forces by name or in detail.
