  • What should you be able to describe by the end of the video?
    Reactivity of group one metals
  • How does the reactivity of group one metals change?
    It increases as we move down the group
  • What is the reason for the change in reactivity of group one metals?
    It is due to the outer electron
  • What are group one metals also known as?
    • Alkaline metals
  • How many electrons do all group one metals have in their outer energy level?
    One electron
  • What happens when lithium reacts with oxygen?
    Lithium forms lithium oxide
  • How does sodium's reaction with oxygen compare to lithium's?
    Sodium reacts more rapidly than lithium
  • What compound does potassium form when reacting with oxygen?
    Potassium oxide
  • How does potassium's reactivity with oxygen compare to sodium and lithium?
    Potassium reacts more rapidly than both
  • What do lithium and oxygen atoms have in common regarding their outer electrons?
    Lithium has one, oxygen has six
  • What happens to lithium's outer electron when it reacts with oxygen?
    It moves to the oxygen atom
  • What charge do lithium ions have after reacting with oxygen?
    Positive one charge
