  3. Families on the Periodic Table • Elements on the periodic table can be grouped into families based 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.

  4. 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 Image: http://www.learner.org/interactives/periodic/groups2.html

  5. ALKALINE EARTH METALS Group 2 • 2 electrons in the outer shell • White and malleable • Reactive, but less than Alkali metals • Conduct electricity

  6. 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.

  7. Halogens Group 17 • 7 electrons in the outer shell • All are non-metals • Very reactive are often bonded with elements from Group 1

  8. 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

  9. Rare Earth Metals • Some are Radioactive • The rare earths are silver, silvery-white, or gray metals. • Conduct electricity

  10. Group—vertical columns of elements that share common properties and have the same number of outer electrons • Period—horizontal rows of elements where the number of the row is the highest level of energy for an element • Metals—these include groups 1-12 and are broken into 3 categories: alkali, alkaline-earth, and transition • Metalloids—mixed into groups 13-16; have some properties of metals, some properties of nonmetals • Nonmetals—groups 14-18; group 17 are called “halogens” (very reactive, poor conductors), and group 18 are the “noble gases” (colorless, odorless gases that do not tend to react with other elements)
