- Groups in Periodic Table
- Reactivity increases as go down
- elements divided into groups
- Group 1 alkali and transition metals have metalic bonding
- Metalic bonds are strong and metals have high melting points and densities
- The type of bonding and structure of a substance determines its properties
- Alkali metals are soft, low density and very reactive. they are not typical metals
- Alkali metals react with water to produce a hydroxide and hydrogen gas
- The group 7 halogens have low melting and boiling points and are coloured
- Halogens react with metals and hydrogen to produce halides
- a more reactive halogen will displace a less reactive halogen from a solution of its salt
- Noble gases have full outer shells and are unreactive
