Metallic Bonding

What are covalent bonds?

Is it ever possible for a polar bond to be ionic? Explain.

Attractions between polar molecules are stronger than nonpolar molecules.

Changes in physical properties: Higher boiling points Dissolves other polar substances

Ionic or Covalent?

Property Ionic Covalent Transfer e- Share e- How made Bond between Metals & Nonmetals Nonmetals Table Position Opposite sides Same sides Dissolve in water Only if polar Yes Consistency Brittle Soft Melting temp High Low State at 20C Solid Any

Metallic Bond

Occurs With Metal Elements Metallic Bonds Occurs With Metal Elements

shared electrons around it Metallic Bond: Attraction between a metal cation and the shared electrons around it

Caused by attraction between moving electrons & positive ions Lattice of metal IONS surrounded by free e- Caused by attraction between moving electrons & positive ions

How does this structure affect the properties of metals? 1. Conduct electricity

Malleability And Ductility

(Bronze) Alloy: 1 or more elements melted together with a metal Makes the metal stronger

Alloy: Atoms cannot slide over each other easily

Bronze: Cu+Sn Brass: Cu+Zn Cast Iron: Fe+C+Si Copper Penny: Cu+Zn Gold Jewelry: Au+Ag+Zn+Ni Stainless steel: Fe+C+Cr+Ni

Stainless Steel: Iron & chromium Doesn’t rust Resists corrosion

Brass: Copper & Zinc * Malleable * Good sound qualities

Bronze: Mostly Copper with Tin added Resists corrosion Lasts a long time
