  1. The Periodic Table and Ionic Bonding:Part 1-Periodic Table Features

  2. Objectives • -Describe where to find metals, nonmetals, and metalloids on a periodic table • -Explain the properties of metals, nonmetals, and metalloids

  3. Periodic Table • Something “periodic” occurs at regular or generally predictable intervals • Periodic Table of Elements – a table of elements, arranged by atomic number, that shows the patterns in their properties • Dmitri Mendeleev devised the 1st in which predictions were made • Element- pure substance made up of one kind of atom

  4. Mendeleev’s Published Periodic Table of Elements Why do you think there are question marks here? Image taken from: http://www.chemsoc.org/networks/learnnet/periodictable/post16/develop/mendeleev.htm

  5. Using the Periodic Table • Boxes that make up the periodic table contain a significant amount of information Atomic Number (number of protons) Element Symbol (capital letter or a capital and lower case) Element Name Atomic Mass (weighted averages)

  6. Elements Using this as a guide, color code your periodic table to show the classes.

  7. 3 Classes of Elements • Metals • Nonmetals • Metalloids

  8. Metals Location • Left of the zigzag (exception  H) Chemical Properties • Few electrons in outer energy levels so lose electrons easily Physical Properties • Ductile, good conductors, malleable, shiny, most are solid @ room temperature

  9. - + + - - + + + + + - - - - + - - + + + + + - - + + - - - - Metals’ Chemical Properties Notice: only 1 electron in outer level 1s22s22p63s1 Notice: only 2 electrons in outer level 1s22s2

  10. Non-Metals Location • Right of the zigzag Chemical Properties • Almost full outer energy levels, so tend to gain electrons; some completely full Physical Properties • Not ductile or malleable, or shiny, poor conductors, most are solid, but some are gas

  11. - + + + + - - - - - - + + + + - - + + + + + + + - + + - - + + - - - - - - - Non-metals’ Chemical Properties Notice: 2 electrons in outer level – FULL 1s2 Notice: 6 electrons in outer level – almost full 1s22s22p4 Notice: 7 electrons in outer level – almost full 1s22s22p5

  12. Metalloids Location • Border zigzag staircase Chemical Properties • Most atoms have ½ (≈) complete set of electrons in outer level Physical Properties • have properties of both metals and non-metals • B, Si, Ge, As, Sb, Te, At

  13. Objectives • -Describe where to find metals, nonmetals, and metalloids on a periodic table • -Explain the properties of metals, nonmetals, and metalloids
