  1. History – Station 1 • Demitri Mendeleev • Credited with the creation of the basis for our modern day table • Not the first to suggest the table • First to create one that predicted the existence of as-yet-undiscovered elements which were later discovered • As of 2012, the periodic table contains 118 confirmed chemical elements. • Developed while making a textbook for his students • Created a graphic organizer of the elements looking for patterns.

  2. Period and Groups – Station 2 When a column goes from top to bottom, it's called a group. The elements in a group have the same number of electrons in their outer orbital (Valence). When you look at a periodic table, each of the rows is considered to be a different period

  3. Reactivity – Station 3 Alkali Metals and Halogens are very reactive because they have either 1 or 7 valence electrons

  4. Families on the Periodic Table – Station 4 • 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.

  5. ALKALI METALS – Station 5 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 Light Blue Image: http://www.learner.org/interactives/periodic/groups2.html

  6. ALKALINE EARTH METALS – Station 6 Group 2 • 2 electrons in the outer shell • White and malleable • Reactive, but less than Alkali metals • Conduct electricity • Color Dark Green

  7. TRANSITION METALS Station 7 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 in a variety of shapes. • Color Dark Blue

  8. BORON FAMILY – Station 8 Group 13 • 3 electrons in the outer shell • Most are metals • Boron is a metalloid • Color Red

  9. CARBON FAMILY – Station 9 Group 14 • 4 electrons in the outer shell • Contains metals, metalloids, and a non-metal Carbon (C) • Color Yellow

  10. NITROGEN FAMILY – Station 10 Group 15 • 5 electrons in the outer shell • Can share electrons to form compounds • Contains metals, metalloids, and non-metals • Color Bright Green

  11. OXYGEN FAMILY – Station 11 Group 16 • 6 electrons in the outer shell • Contains metals, metalloids, and non-metals • Reactive • Color ORANGE

  12. Halogens – Station 12 Group 17 • 7 electrons in the outer shell • All are non-metals • Very reactive are often bonded with elements from Group 1 • Color Yellow

  13. Noble Gases – Station 13 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 • Color Grey

  14. Rare Earth Metals – Station 14 • Some are Radioactive • The rare earths are silver, silvery-white, or gray metals. • Conduct electricity • Color Violet

  15. Color by Type – Station 15 • Get your full size Periodic Table • Color Code the periodic table as below • Make a key or legend as seen below
