Properties of Metals

• The Arrangement of metal cations and the strong characteristic of metallic bond, makes delocalized electrons move
• Luster - metals are lustrous or shiny because of loose electrons
• Malleability - ability to flatten into thin sheets because electrons can easily slide over one another
• Ductility - ability to stretch into wires because the delocalized electrons can freely move
• Hardness - to resist breaking because of strong metallic bond
• Conductivity - good conductors of heat and electricity because of delocalized electrons
• High Density - metals are this because they are too heavy because atoms are arranged closely to one another
• High Melting Point -metals have this because the strength of the metallic bonding
• Metal Alloys - when one type of metal combined with another type of metal
• Alloy - homogenous mixture resulted from combination of two or more elements which will result in having metallic properties
• Alloys has greater strength and capacity than pure metals
• Alnico - magnets
• Brass - plumbing, hardware, lighting
• Bronze - bearings, bells, medals
• Cast Iron - Cooking pots
• Dental Amalgam - dental fillings
• Lead Shot - shotgun shells
• Stainless Steel - Surgical Instruments
• Sterling Silver - Tableware, jewelry
