- C2: Bonding, Structure and Properties of Matter
- States of Matter
- Three states of matter: Solids, Liquids, Gases
- Changing States
- State Symbols
- Solid (s)
- Liquid (l)
- Gas (g)
- Aqueous (aq)
- Ionic Compounds
- Chemical Bonds
- Ionic Bonds
- Covalent Bonding
- Metallic Bonding
- Ions are formed when atoms gain or lose electrons (giving them an overall charge)
- Ionic bond is a strong electrostatic force of attraction between the positive metal ion and the negative non-metal ion
- Metals that loose= positively charged
- Metal that gains = negatively charged
- Properties
- Giant Structures
- Held together by strong forces of attraction
- High m.p and b.p
- Do not conduct electricity
- Do conduct when molten or in solution
- Chemical Bonds
- Covalent Compounds
- Covalent Bonding
- Shared pair of electrons
- Occur in non- metals
- Very strong
- Small molecules
- No overall electrical charge
- Low melting and boiling points
- Weak intermolecular
- Larger molecules have stronger intermecular forces
- Giant Covalent Structure
- Diamond (form of carbon)
- Lattice structure
- Each carbon atom forms 4 strong covalent bonds with other carbons
- No charged particles
- Graphite
- Each carbon atom forms 3 covalent bonds
- Layered, hexagonal structure (weak inter molecular forces)
- Conduct heat and electricity
- Diamond (form of carbon)
- Covalent Bonding
- Metals and Special Materials
- Graphene (form of carbon) (single layer of graphite)
- Fullerenes
- Hollow shape (tubes, balls and cages)
- Polymers
- Very large molecules, strong covalent bonds
- Solid at room temperature
- Metallic Bonding
- Metals, alloys
- Giant structure, electrons in outer shell are delocalised
- Electrostatic atttraction
- States of Matter
