  1. Review

  2. Reading the Periodic Table: Classification • Nonmetals, Metals, Metalloids, Noble gases

  3. Alkali Family: 1 e- in the valence shell Halogen Family: 7 e- in the valence shell Down the Periodic Table • Family:Are arranged vertically down the periodic table (columns or group, 1- 18 or 1-8 A,B) • These elements have the same number electrons in the outer most shells, the valence shell.

  4. Across the Periodic Table • Periods:Are arranged horizontally across the periodic table (rows 1-7) • These elements have the same number of valence shells. 2nd Period 6th Period

  5. Periodic Table: Metallic arrangement • Layout of the Periodic Table: Metals vs. nonmetals Nonmetals Metals

  6. Metals, Nonmetals, Metalloids • How can you identify a metal? • What are its properties? • What about the less common nonmetals? • What are their properties? • And what the heck is a metalloid?

  7. Metals • Metals are lustrous (shiny), malleable, ductile, and are good conductors of heat and electricity. • They are mostly solids at room temp. • What is one exception?

  8. Nonmetals • Nonmetals are the opposite. • They are dull, brittle, nonconductors (insulators). • Some are solid, but many are gases, and Bromine is a liquid.

  9. Metalloids • Metalloids, aka semi-metals are just that. • They have characteristics of both metals and nonmetals. • They are lustrousbut brittle. • And they are semiconductors.

  10. Noble Gases • Found in group 18 (the last column of the periodic table.) • Do not react easily with other elements, as they have a full outer shell.

  11. Periodic Table Expanded View • The way the periodic table usually seen is a compress view, placing the Lanthanides and actinides at the bottom of the stable. • The Periodic Table can be arrange by subshells. The s-block is Group IA and & IIA, the p-block is Group IIIA - VIIIA. The d-block is the transition metals, and the f-block are the Lanthanides and Actinide metals

  12. Summary • Periodic Table: Map of the Building block of matter • Type: Metal, metalloid and Nonmetal • Groupings: Representative or main, transition and Lanthanide/Actanides • Family: Elements in the same column have similar chemical property because of similar valence electrons • Alkali, Alkaline, chalcogens, halogens, noble gases • Period: Elements in the same row have valence electrons in the same shell.

  13. Practice Quiz • Draw a bohr-Rutherford diagram of a sodium atom • Draw a lewis-dot diagram of Aluminum • What do we call the horizontal rows? • What do we call the vertical columns? • What is the name for the 2nd column?
