- C2 - Bonding,
Structure and the properties of Matter
- States Of Matter
- Solid
- Close together; regular pattern.
- Vibrates on the spot
- Fixed shape cannot flow
- Cannot be compressed or squashed
- Liquid
- Close together
- Move around each other
- Flows and takes shape of container
- Cannot be compressed or squashed.
- Gas
- Far apart
- Random arrangement
- Flow and fill their container
- Can be compressed or squash
- Move quickly in all directions
- State symbols
- l - liquid
- s - solid
- g - gas
- aq - aqueous solution
- Solid
- Bonding
- Ionic
- between a metal and a non-metal.
- No definite shape
- high melting point
- high boiling point
- Solid at room temperature.
- Transfer of electrons between atoms.
- Covalent
- Between two non-metals
- Share of electrons between atoms
- Definite shape
- low melting point
- low boiling point
- liquid or gaseous at room temperature
- Ionic
- Structure
- Metals
- delocalised electrons
- allows conduction of electricity
- layers
- soft
- delocalised electrons
- Giant Covalent
- High melting and boiling points
- Insoluble in water
- Hard and do not conduct electricity (except graphite)
- Huge network of atoms held together by covalent bonds
- Giant Ionic Lattice
- Strong electrostatic forces holding oppositely charged ions together.
- High melting and boiling point
- regular arrangement of ions
- Only conducts electricity when molten or dissolved
- Ions need to be free to move
- Simple Molecule
- Covalently bonded atoms
- 1 molecule
- Covalently bonded atoms
- Metals
- States Of Matter
- Liquids evaporate into a gas when they reach a boiling point(*c)
- Solids melt into a liquid when they reach a melting point(*c)
- Gases condense in to liquids
- Liquids freeze to become solids
