- Structure and Bonding
- Ionic Compounds
- Ionic Bonding
- Electrostatic forces of attraction
- Between positively and negatively charged ions
- Properties
- High melting and boiling point
- Strong forces between oppositely charge ions
- Large amountthermalenergy needed
- Strong forces between oppositely charge ions
- High melting and boiling point
- Strong bonds between atoms in a small molecule
- Between a metal and a non-metal
- Ionic Bonding
- Carbon
- Diamond
- Very hard
- Carbon atoms bonded four others
- Strong bonds
- Doesn't conduct
- All electrons are bonded
- Very hard
- Graphite
- Soft
- Giant layers of atoms can slide over each other easily
- Weak forces
- Conducts electricity
- Soft
- Diamond
- Metals and alloys
- Metallic bonding
- Metal ions held together by electrons from the outermost shell
- The electrons in the metal are free to move around
- Metal ions held together by electrons from the outermost shell
- Alloys are harder than pure metals
- Alloys have different size atoms
- Makes it harder to slide over each other because the rows of atoms are disorted
- Alloys can conduct and metals can't
- Alloys have a sea of delocalised electrons
