Bonding – Topic 4 & 14 – Ionic, Covalent and Metallic bonding

Here is a pretty cool youtube video that your students will probably love -it is quite simplistic though, but not bad for students to view in their own time. You could ask your students to use this as a starting point for explaining (in more depth) about the different types of bonding (maybe for a homework exercise?) C6o-eqGUBCY

Electrongeativity

To effectively teach topic 3.2 (Physical trends) of the Periodicity unit, you need to introduce the students to the concept of electronegativity. In order to assist your teaching, the following video may help. You should also emphasize to the students that electronegativity is only found in covalent bonding (and not the common misconception, that it is found in all bonds). OgAEnuYKcPg
