For ionic bonding the particles are oppositely charged ions. For covalent bonding the particles are atoms that share pairs of electrons. For metallic bonding the particles are that share delocalised electrons. Ionic bonding occurs in compounds formed from metals combined with Covalent bonding occurs in non-metallic elements and in compounds of non-metals. Metallic bonding occurs in metallic elements and alloys. Describe the nature and arrangement of the three types of chemical bonds: ionic, covalent and metallic. Describe the compounds each type of chemical bond occurs in. Explain chemical bonding in terms of electrostatic forces and the transfer or sharing of electrons. 1 Introduction to bonding – circus of activities.

Chemical bonding provides the rules models – discuss what the parts represent. Atoms – not solid spheres. Bonds – not physical attachments but akin to push and pull of magnetic forces types of bond lie along a scale. Like picking out colours metals.
