Alkali Metals
3
Alkali Metals
  • Group 1 on the periodic table

4
Alkali Metals
  • Group 1 on the periodic table
  • One valence electron

5
Alkali Metals
  • Group 1 on the periodic table
  • One valence electron
  • Most reactive metals

6
Alkali Metals
  • Group 1 on the periodic table
  • One valence electron
  • Most reactive metals
  • Low melting and boiling points make them soft

7
Alkali Metals
  • Group 1 on the periodic table
  • One valence electron
  • Most reactive metals
  • Low melting and boiling points make them soft
  • Not found in their pure state in nature

8
Alkali Metals
  • Group 1 on the periodic table
  • One valence electron
  • Most reactive metals
  • Low melting and boiling points make them soft
  • Not found in their pure state in nature
  • React with water to form basic (alkaline)
    solutions

9
Alkali Metals
  • Group 1 on the periodic table
  • One valence electron
  • Most reactive metals
  • Low melting and boiling points make them soft
  • Not found in their pure state in nature
  • React with water to form basic (alkaline)
    solutions
  • Compounds are white, solutions are colorless

Transition Metals
  • Groups 3-12 on the periodic table

21
Transition Metals
  • Groups 3-12 on the periodic table
  • Number of valence electrons vary (usually 1-4)

  • Higher melting and boiling points than other
    metals

26

  • Higher melting and boiling points than other
    metals
  • Mercury is the only metal that is liquid at room
    temperature

27
Rare Earth Metals
  • Two rows at the very bottom of the periodic table.

28
Rare Earth Metals
  • Two rows at the very bottom of the periodic
    table.
  • Due to their large size, most of these elements
    are radioactive.

29
Rare Earth Metals
  • Two rows at the very bottom of the periodic
    table.
  • Due to their large size, most of these elements
    are radioactive.
  • Typically not found in a lot of compounds,
    although it is possible.

  • Typically used as a filler gas when space needs
    to be taken up without a reaction taking place.
