Chemical Bonds Part 4 Metalic Bonding

How Metals Bond Metallic bonds account for many physical characteristics of metals, such as Strength Malleability Ductility conduction of heat and electricity luster

A Few Facts The outer electrons of metals are not very strongly held by the nucleus So they stray easily and can move from one atom to the next Think of a “sea of electrons” Outer energy levels overlap like covalent bonds

Bond found in metals; holds metal atoms together very strongly Metallic Bonds Bond found in metals; holds metal atoms together very strongly

Metallic Bonds: Mellow dogs with plenty of bones to go around

Metals Form Alloys Metals do not combine with metals. They form Alloys which is a solution of a metal in a metal. Examples are steel, brass, bronze and pewter.
