Learning Objectives

Indicator: B9.1.1.1.2 - Discuss the formation of binary chemical compounds.

By the end of the lesson, learners can:

Distinguish among elements, molecules, ions and compounds using their own examples.
Write the molecular formula of binary compounds such as water, carbon (IV) oxide, iron (II) sulphide and magnesium oxide.
Describe how binary chemical compounds are formed from their constituent elements.
Compare and contrast binary chemical compounds based on their composition and properties.
Construct models to represent binary chemical compounds using everyday materials.
