Bonding in Metals pp. 198-203 Chapter 5-4

Questions about metals: How do metals bond with other elements? How are alloys formed? Why do metals form alloys? How do metal atoms bond together? What are the properties of metals? What are some common alloys?

Bonding in Metals: 1. How do metals bond with other elements? Metals lose or share 1, 2 or 3 electrons Metals can either combine with other metals or nonmetals from the periodic table When metal atoms combine, they form regular (crystalline-like) patterns in a way that allows valence electrons to move from atom to atom

How do metal atoms bond together?

Bonding in Metals 2. How are alloys formed? Metals form alloys by bonding with other elements

Bonding in Metals 3. Why do metals form alloys? Alloys are generally stronger, less reactive and resist rust better than pure metals

4. How do metal atoms bond together? In a metallic bond, the metallic crystal has positive metal ions which are attracted to the many electrons around it.

5. Properties of Metals: Because of the way that metals bond, they have: Malleability (they can bend) Luster (they are shiny) Electrical and Heat Conductivity Ductility (they can form wires)

Pewter: Tin, Copper and Lead 6. Common Metal Alloys Some Common Alloys: Steel: Iron and Carbon Brass: Copper and Zinc Bronze: Copper and Tin Pewter: Tin, Copper and Lead

Rose Gold: Gold and Copper Common Metal Alloys Some Common Alloys of Gold: Rose Gold: Gold and Copper White Gold: Gold with Nickel or Gold with Palladium
