PERIODIC TABLE
- Groups
- GROUP I - Alkali Metals
- Physical properties
- Grey solids
- Dull on outside, shiny inside
- Low melting and boiling points
- Low densities --> float on water
- Soft, easily cut
- Grey solids
- Chemical properties
- Very reactive - stored under oil
- burn on heating to form oxides
- React violently with cold water
- Very reactive - stored under oil
- Physical properties
- GROUP II - Alkaline Earth Metals
- Physical properties
- Grey solids
- Dull on outside, shiny inside
- Higher melting and boiling points than G1
- Harder than G1 elements
- More dense than water --> sink
- Grey solids
- Chemical properties
- Reactive metals
- Mg and Ca not stored under oil
- burn on heating to form oxides
- Most will react will cold water, Mg - heated with steam
- Reactive metals
- Physical properties
- GROUP VII - Halogens
- Physical properties
- They are coloured
- Fluorine - Green gas
- Chlorine - Green gas
- Bromine - Orange liquid
- Iodine - Black solid which sublimes to a purple gas
- Fluorine - Green gas
- Melting and boiling points are low
- Extremely toxic
- They are coloured
- Chemical properties
- Reactivity DECREASES down the group
- Reactive non- metals
- React with water to form acidic solutions (eg) bleach
- They undergo displacement reactions
- Reactivity DECREASES down the group
- Physical properties
- GROUP 0 - Noble Gases
- Single Atoms
