Slide 2 - Poll

  • identify trends in groups, given information about the elements  
  • describe the Group I alkali metals, lithium, sodium, and potassium, as relatively soft metals with general trends down the group, limited to:
  • (a) decreasing melting point
  • (b) increasing density
  • (c) increasing reactivity  
  • predict the properties of other elements in Group I, given information about the elements
