1. Chapter 6 Review

2. The Periodic Table  Groups go up and down  Periods go left to right  Representative elements are found in groups 1A- 8A  All other groups are transition elements

3. Element Classification  Metals- shiny, solid at room temperature, good conductors of electricity  Found on the left side of the periodic table  Semi-metals- have characteristics of both metals and non-metals are located by the dark line of the periodic table.

4.  Non-metals- gases or brittle dull-looking solids and poor conductors of electricity. Located on the right side of the periodic table.

5. Group Classification  Group 1A-Alkali Metals  Group 2A- Alkaline Earth metals  Group 7A- Halogens  Group 8A- Noble gases  Elements in the same group have similar properties.

6. Periodic Trends  Atomic Radius- the size of the element. Increases down and to the left.

7. Periodic Trends  Ionization Energy-the energy required to remove an electron.  Electronegativity- the energy required to attract an electron.  Both increase up and to the right.

8. Perioidic Trend  Ionic Radius-a positive or negatively charged atoms.  Positive (cation) lose an electron and small  Negative (anion) gain an electron and large

9. Valence Electrons  Group number equals the number of valence electrons.  Valence electrons are located on the outermost energy level.  Valence electrons are the ones involved in bonding.
