Families on the Periodic Table Elements on the periodic table can be grouped into families bases on their chemical properties. Each family has a specific name to differentiate it from the other families in the periodic table. Elements in each family react differently with other elements.
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 Color yellow Image: http://www.learner.org/interactives/periodic/groups2.html
ALKALINE EARTH METALS Group 2 2 electrons in the outer shell White and malleable Reactive, but less than Alkali metals Conduct electricity TRANSITION METALS
Groups in the middle 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 in a variety
of shapes. BORON FAMILY Group 3 3 electrons in the outer shell Most are metals Boron is a metalloid CARBON FAMILY Group 4
4 electrons in the outer shell Contains metals, metalloids, and a non-metal Carbon (C) NITROGEN FAMILY Group 5 5 electrons in the outer shell
Can share electrons to form compounds Contains metals, metalloids, and non-metals OXYGEN FAMILY Group 6 6 electrons in the outer shell Contains
metals, metalloids, and non-metals Reactive Halogens Group 7 7 electrons in the outer shell All are nonmetals Very reactive are often bonded
with elements from Group 1 Noble Gases Group 8 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 Rare Earth Metals Some are Radioactive The rare earths are silver, silverywhite, or
