ALKALI METALS Group 1 Hydrogen is not a member, it is a non-metal 1 electron in the outer shell Soft and silvery metals Very reactive, esp. with water Conduct electricity http://www.youtube.com/watch?feature=player_embedded&v=6ZY6d6jrq-0 Episode 402

ALKALINE EARTH METALS Group 2 2 electrons in the outer shell White and malleable Reactive, but less than Alkali metals Conduct electricity http://www.youtube.com/watch?v=B2ZPrg9IVEo&feature=player_embedded Episode 402

TRANSITION METALS Groups 3-12 Good conductors of heat and electricity. Some are used for jewelry. The transition metals are able to put up to 32 electrons in their second to last shell. Can bond with many elements to form a variety of compounds. Episode 402

BORON FAMILY Group 13 3 electrons in the outer shell Most are metals Boron is a metalloid Episode 402

CARBON FAMILY Group 14 4 electrons in the outer shell Contains metals, metalloids, and a non-metal Carbon (C) Episode 402

NITROGEN FAMILY Group 15 5 electrons in the outer shell Can share electrons to form compounds Contains metals, metalloids, and non-metals Episode 402

OXYGEN FAMILY Group 16 6 electrons in the outer shell Contains metalloids, and non-metals Reactive Episode 402

Halogens Group 17 7 electrons in the outer shell All are non-metals Very reactive are often bonded with elements from Group 1 http://www.youtube.com/watch?v=u2ogMUDBaf4&feature=player_embedded Episode 402

Noble Gases Group 18 Exist as gases Non-metals 8 electrons in the outer shell = Full Helium (He) has only 2 electrons in the outer shell = Full Not reactive with other elements Episode 402

Rare Earth Metals Lanthanides Actinides Some are Radioactive The rare earths are silver, silvery-white, or gray metals. Conduct electricity Lanthanides Actinides Episode 402
