Alkali metals (Group 1)

• Alkali metals are the metals in Group 1 of the Periodic Table
• Group 1 are known as alkali metals and are solid at room temperature
• Soft metals can be easily cut with a knife.
• The further down the group, the easier the metals are to cut.
• Low density metals are able to float on top of water.
• The melting point of the alkali metals decreases as you go down the group.
• The boiling point of the alkali metals decreases as you go down the group.
• The density trend of the metals is that it increases as you go down the group.
• The metals react with water producing the metal hydroxide and hydrogen.
• As you go down the group, the metals get more reactive.
• Group 1 are known as alkali metals and are solid at room temperature
• Alkali metals are stored in oil to prevent them from reacting with the oxygen in the air.
• What are the properties of metals?

  Malleable - can be hammered without breaking

  Magnetic

  Conductors

  Ductile - can be drawn into a thin wire

  Lustrous - shiny when polished

  High melting and boiling points
