• what group?

  group 1
• good conductors of..?

  heat and electricity

  freshly cut
• React with water to form?

  increases
• Which elements are stored in oil to keep air and water away?


  Lithium,sodium,potassium
• Which elements are less dense than water so float?


  lithium,sodium,potassium
• low/high melting points?

  low
• what state?

  solids
• soft/hard?

  soft so can be cut with knife
• why does it become more reactive going down group?

  Atoms get larger meaning outer electron is further away from positive nucleus therefore attraction is weaker so electron is more easily lost
