- Bonding, Structure and properties
- Covalent bonding
- Non-metal and a Non-metal
- electrons are shared
- Some are Small molecules e.g. H2O, CO2, CH4
- Polymers can be made from many smaller molecules e.g. polyethene
- solid at room temperature
- Gases or liquids at room temperature
- Low melting boiling points
- Weak forces between molecules
- Polymers can be made from many smaller molecules e.g. polyethene
- Some have giant structures e.g. diamond
- Solid with a very high melting point
- Strong covalent bonds between atoms.
- Carbon only
- Diamond
- 4 covalent bonds hard, high melting point and does not conduct electricity
- Graphite
- 3 covalent bonds arranged in layers so slide and free electrons allow electrical conductivity
- Graphene
- single layer of graphite used in electronics and composites
- Fullerenes
- Hollow shapes of carbon 5,6 or 7 bonds
- nanotubes used in nanotechnology and electronics
- Hollow shapes of carbon 5,6 or 7 bonds
- Diamond
- Carbon only
- Dot and cross diagrams
- Ionic bonding
- Atom loses or gains an electron
- Metal and a Non-metal
- Dot and cross diagrams
- Metallic bonding
- Most are solid at room temperatureUntitled
- PURE METALS Atoms arranged in layers - are malleable (can be bent and shaped)
- Free electrons allow electrical conductivity
- ALLOYS Different size metal atoms make metals harder
- Covalent bonding
- Quantitative chemistry
- Chemical changes
