  • 1. Elements may be classified (put into sets) in One way : metals or non-metals (conductors or non-conductors)Chemists classify elements by arranging them in the Periodic Table.In a group, all the elements present have similar chemical properties.Group I (1) the Alkali MetalsAll of the elements in Group I are metals.They are soft and easily cut.When freshly cut they have a bright, shiny, silvery appearance.All react vigorously with air and water so are stored under oil.Solutions of their compounds are alkaline in nature.They become more reactive going down the Periodic Table.
  • 2. Elements may be classified (put into sets) in One way : metals or non-metals (conductors or non-conductors) Chemists classify elements by arranging them in the Periodic Table. In a group, all the elements present have similar chemical properties.Group VII (7) the HalogensAll are non-metals.Most are very reactive.They form salts with the metals
  • 3. Elements may be classified (put into sets) in One way : metals or non-metals (conductors or non-conductors) Chemists classify elements by arranging them in the Periodic Table. In a group, all the elements present have similar chemical properties.Group 0 (or 8) the Noble GasesAll members are very uncreative gases.They are used in advertising signs
