1. Getting To Know The Periodic Table

2. Forming the Periodic Table Dimitri Mendeleev Mendeleev was the first scientist to notice the relationship between the elements – Arranged his periodic table by atomic mass – Said properties of unknown elements could be predicted by the properties of elements around the missing element Moseley later discovered that the periodic nature of the elements was associated with atomic number, not atomic mass

4. Reading The Periodic Table Periods: Rows of the Periodic Table (going left to right) Periods go Horizontally on the Periodic Table Example: Li, Be, B, C, N, O, F, and Ne are in the same period. Draw in arrows and label showing the direction of periods on the table. Periods

5. Reading the Periodic Table Groups: (Families) The vertical columns of the Periodic Table (going from top to the bottom) Sometimes called columns Draw in arrows and show the direction of groups in the periodic table. Groups

6. What does the information in the box tell me? 6 C 12.01 Atomic Number = # of protons Atomic Mass = # of protons plus neutrons Atomic Symbol

7. METALS Most common elements on the periodic table. Found to the left of the stair-step. Characteristics of Metals: – Good Conductors of electricity – Shiny surfaces – Malleable – Ductile The only element found to the left of the stair step that is NOT a metal is HYDROGEN!!

8. Metals BLUE Shade the metals on the periodic table BLUE. HHe Li Be BCNOFNe NaMgAlSiPSClAr KCaScTiVCrMnFeCoNiCuZnGaGeAsSeBrKr RbSrYZrNbMoTcRuRhPdAgCdInSnSbTeIXe CsBaLaHfTaWReOsIrPtAuHgTlPbBiPoAtRn FrRaAcRfDbSgBhHsMtDsRgUub CePrNdPmSmEuGdTbDyHoErTmYbLu ThPaUNpPuAmCmBkCfEsFmMdNoLr

9. METALLOIDS Elements between the metals and nonmetals. They touch the “stair-step” of the Periodic Table. They have characteristics of both metals and nonmetals.

10. METALLOIDS YELLOW Shade the metalloids YELLOW on the table. 1 IA metalloids 18 VIIIA Li Be BCNOFNe NaMg 3 IIIB4 IV5 VB6 VIB 7 VIIB 8 VIIIB 9 VIIIB 10 VIIIB 11 IB12 IIB AlSiPSClAr KCaScTiVCrMnFeCoNiCuZnGaGeAsSeBrKr RbSrYZrNbMoTcRuRhPdAgCdInSnSbTeIXe CsBaLaHfTaWReOsIrPtAuHgTlPbBiPoAtRn FrRaAcRfDbSgBhHsMtDsRgUub CePrNdPmSmEuGdTbDyHoErTmYbLu ThPaUNpPuAmCmBkCfEsFmMdNoLr

11. NONMETALS Elements that are found to the RIGHT of the stair step. Characteristics of Nonmetals: – Dull surfaces – Poor conductors of electricity – Brittle solids

12. NONMETALS GREEN Color the nonmetals GREEN on the Periodic Table H nonmetals He Li Be BCNOFNe NaMgAlSiPSClAr KCaScTiVCrMnFeCoNiCuZnGaGeAsSeBrKr RbSrYZrNbMoTcRuRhPdAgCdInSnSbTeIXe CsBaLaHfTaWReOsIrPtAuHgTlPbBiPoAtRn FrRaAcRfDbSgBhHsMtDsRgUub CePrNdPmSmEuGdTbDyHoErTmYbLu ThPaUNpPuAmCmBkCfEsFmMdNoLr

13. Groups/Families of the Periodic Table

14. GROUP 1: Alkali Metals Most reactive metals on the PT Rarely found free in nature Bond easily with other elements Charge of 1—1 valence electron Shade in the Alkali Metals

15. GROUP 2 : Alkaline-Earth Metals Still quite reactive Charge of 2—2 valence electrons Shade in the Alkaline-Earth elements

16. Groups 3-12: The Transition Metals Found freely and in compounds in nature Charge is usually 2 but can vary—usually 2 valence electrons Shade in the Transition Metals

17. Group 13: Boron Group First group after the transition metals Charge is 3—3 valence electrons Shade in the Boron Group

18. Group 14: The Carbon Group Contains elements that can form unusual bonds (carbon and silicon) Charge is +4 or -4—contains 4 valence electrons Shade in the Carbon Group

19. Group 15: The Nitrogen Group Charge is -3—contains 5 valence electrons Many elements in this group can be found in fertilizers Shade in the Nitrogen Group

20. Group 16: The Oxygen Group Also known as the chalcogens Charge is -2. It has 6 valence electrons Shade in the Oxygen Group

21. Group 17: The Halogens Most reactive nonmetals charge is -1—7 valence electrons Shade in the Halogens

22. Group 18: The Noble Gases Known as the Inert Gases Nonreactive Charge is 0—2 or 8 valence electrons DO NOT combine with other elements

23. Lanthanides and Actinides Found at the bottom of the Periodic Table At the bottom to make the Periodic Table easier to read Part of the Transition Group Shade in the Lanthanides and Actinides

24. Solids, Liquids, and Gases Shade the solids GREEN Shade the Liquids BLUE Shade the Gases YELLOW

25. Important Facts about the Periodic Table: Elements are arranged horizontally by increasing atomic number (# of protons) The more reactive elements are at the BOTTOM of the Periodic Table Elements in the same family share similar characteristics An element’s identity is related to the number of protons in the atom’s nucleus
