1. Metals Non-Metals and Metalloids

2. Metals Lose electrons during reactions Form Ionic Bonds Over 80% of the elements on the table Most metallic elements are at the bottom of the group

4. Non-Metals Liquids/Gases Right of Staircase Gain electrons to form ionic bonds(negative charges) Share electrons to form covalent bonds

6. Metalloids Have properties of both metals and non-metals Called semi-metals as well On the staircase B, Ge, Si, As, Sb, Te, At)

8. Metals/Non- Metals/Metalloids Metals Solid at Room Temperature Density greater than 1 Malleable Ductile (Bent, Formed) Luster (Shine) Conduct Electricity Low Ionization Energy Low Electronegativity Non-metals Liquid or Gas at Room Temperature Density less than 1 Brittle Not Ductile No Luster (Dull) Most Do not Conduct High Ionization Energy High Electronegativity

9. What are the Diatomic Elements? Elements that are never found alone in nature Always part of a compound or molecule They are: H 2, N 2, O 2, F 2, Cl 2, Br 2, I 2 Think HOFBrINCl These are the only elements that can bond with themselves

11. How does the Number 7 help me Identify the Diatomics?
