• what are group 1 elements called?

  Alkali metals
• what are the alkali metals?

  lithium, sodium, potassium, rubidium, caesium, francium
• how are the group 1 elements densitie?

  low densities
• are they soft or hard?

  soft enough to cut with a knife
• reactivity?

  very reactive
• trend in reactivity?

  reactivity increases as you go down the group
• what happens when alkali metals are put in water?

  they react vigourosly to form metal hydroxides and hydrogen gas
• how do all alkali metals react?

  in a similar way
• how does the reaction change based on reactivity?

  the more reactive the alkali metal is the more vigorous the reaction
• what happens when an alkali metal reacts with oxygen?

  they form metal oxides
• metal oxides with different alkali metals

  different alkali metals produce different metal oxides
• trends in melting and boiling points?

  melting and boiling points decrease as you move down the group
