- Chemistry Chapter 5
- The periodic table
- Arranged in order of atomic number
- Noble gases are monatomic gases
- Group 1 + 2 = reactive metals
- Middle chunk = transition elements
- Right side = non-metals (4 across)
- Group 0 = noble gases
- Alkali metals
- Stored in oil
- Reaction with water
- Floats, fizzes (hydrogen) and moves around
- Potassium's hydrogen catches fire
- Water becomes very alkali
- Floats, fizzes (hydrogen) and moves around
- Reaction with non-metals
- Vigorous
- Produces white solid
- Transition elements
- Make coloured compounds
- Used as catalysts in industry
- Group 7 (halogens)
- Reaction with hydrogen
- Start explosive - get less reactive going down group
- Displacement in an aqueous solution
- A more reactive halogen will displace a less reactive hologen
- eg. chlorine + potassium bromide = potassium chloride + bromine
- A more reactive halogen will displace a less reactive hologen
- Reaction with hydrogen
