The periodic table is an essential tool for the chemist. It provides us with the understanding to begin to rationalise and explain our observations as we explore the world of the elements. Whilst the chemistry of the alkali metals and halogens can seem simple to explain, the chemical properties of other elements can require greater insight and an appreciation of bonding. Common textbook answers to questions may not be as complete as we like to think.
After working through this topic you will be able to:
- evaluate explanations for the solublity of Group 2 compounds
- use the atomic model to explore variations in bonding and compounds of Group 15 elements
- consider practical ways to introduce students to the ideas of supply risk and scarcity that impact how we use elements in the real world; and
- use a simple experiment to explore the thermal stability of metal carbonates
