Group 1 Elements

View mindmap
  • Group 1
    • They are called alkali metals
    • They have similar properties to other metals.
      • malleable
      • Conduct electricity
    • Other Phyiscal Properties
      • low melting points
      • soft
      • easily cut
      • very reactive
    • They are easily oxidised and burn brightly in air
    • These atoms have one electron in their outer shell
      • When they react with non-metals, the outer electron is transferred to the non-metal
      • Going down Group 1 the atoms get larger
      • This explains the trend in reactivity
    • Caesium is highly reactive in water and therefore dangerous to do in school
