Structure and bonding: 9.3.6: Covalent bonding
- To describe the covalent bond as a shared pair of electrons that holds
together the two positive nuclear centres of a molecule
- To understand that sharing bonding pairs of electrons gives a full
outer shell (octet rule)
- To understand that each nuclear centre has the effective control of
one of the two electrons in a pair
- To know that covalent bonding takes place between non-metal atoms
- To draw molecules representing binary compounds
Powerpoint and flash demonstrations
Student follow up
The students are to construct simple dot cross diagrams to represent
a series of covalent molecules.
Remind the students that atoms cannot exist on their own under normal
The non-metallic elements must be covalent.
