- C5 - Chemicals of the Natural Environment
- The Earth's Sphere
- Atmosphere
- Atmosphere: The layer of gases that surround the Earth.
- E.g. Oxygen, Carbon Dioxide, Nitrogen.
- Atmosphere: The layer of gases that surround the Earth.
- Hydrosphere
- Hydrosphere: All the water on Earth.
- E.g. Oceans, Rivers, Lakes.
- Hydrosphere: All the water on Earth.
- Biosphere
- Biosphere: All living things on Earth.
- E.g. Plants, Animals.
- Biosphere: All living things on Earth.
- Lithosphere
- Lithosphere: The Earth's crust and the top part of the mantle
- E.g. Copper, Sodium Chloride, Coal, Sulfur, Graphite.
- Oxygen 46.6%
- Silicon 27.7%
- Aluminium 8.1%
- Lithosphere: The Earth's crust and the top part of the mantle
- Atmosphere
- Covalent Bonding
- Occures between non-metals.
- Generally forms small molecules.
- Atoms with nearly a full outer shell will share electrons.
- The sharing of electrons.
- Simplete Covalent Structure

- Simplete Covalent Structure
- Low melting point.
- Non-metals
- Not soluble in water.
- Giant Covalent Structure
- Non-metals
- Not soluble in water
- Hard crystalline solid
- High melting point
- Ionic Bodning
- Occurs between non-metals.
- One atom loses electrons other gains
- Forms very strong bond
- Oppositely charged ions strongly attracted to each other.
- Ionic Strutcture
- High melting points.
- Hard crystalline solid
- Metal and non-metal
- Electrical conductor in solution or molten
- Precipitates
- When two solutions mix, react to form an insoluble product.
- Insoluble product - Precipitate.
- Makes solution go cloduy.
- E.g. lead nitrate and potassium iodide produces yellow precipitate - Lead iodide
- Makes solution go cloduy.
- Diamond
- Very Strong
- High melting and boiling point.
- Graphite
- Conducts electricity.
- Forms in layers
- Graphite
- Insoluble in water
- Graphite
- Conducts electricity.
- Forms in layers
- Graphite
- Does not conduct electricity
- Reactivity Series
- MOST REACTIVE Potassium, sodium, calcium, magnesium, aluminium
- Separated by electrolysis
- MIDDLE REACTIVE Zic, iron, tin, lead, copper
- Reduction of ores using carbon
- LEAST REACTIVE silver, gold
- Metals occur uncmbined (they are pure).
- MOST REACTIVE Potassium, sodium, calcium, magnesium, aluminium
