Group 1: Alkali Metals

• What are the properties of alkali metals?

  Good conductors

  Shiny when cut open

  Soft

  Low melting and boiling points

  Low densities
• What happens to reactivity of alkali metals?

  Reactivity increases as you go down the group
• What happens when alkali metals react with oxygen?

  They tarnish (become dull)
• What happens when lithium reacts with water?

  Fizzes

  Floats

  Moves on the water
• What happens when sodium reacts with water

  Fizzes

  Floats

  Moves quicker than Lithium

  Melts into a ball
• What happens when potassium reacts with water?

  Floats

  Fizzes

  Moves the fastest

  Melts into a ball

  Burns with a lilac flame
• Why are alkali metals stored in oil?

  To prevent reaction with oxygen or water in the atmosphere
