- Chemical Bonding
- Covalent
- Non-metallic elements
- Join by sharing electrons
- Ionic
- Metallic and non-metallic
- Metal atoms lose electrons to form positive ions
- Atoms of non-metals gain electrons to form negative ions
- Ions have stable structure of a noble gas
- Oppositely charged ions attract each other in the compound
- When 2+ elements react together, compounds are formed
- Atoms join in two ways
- Sharing electrons
- Transferring electrons
- Atoms join in two ways
- Group number = number of electrons in outer shell
- Group 1 - 1 electron in outer shell
- Group 7 - 7 electrons in outer shell
- Covalent
