1. Bonding

2. This presentation shows two types of bonding. Ionic bonding Covalent bonding Click on the type of bonding you want to view.

3. Ionic Bonding Ionic bonds form between metals and non- metals Metal atoms lose electrons to form positive ions Non-metal atoms gain electrons to form negative ions The oppositely charged ions attract one another
