The structure of metals By: Dalton, and Austin
Metallic Bonds • A metallic bond is the attraction between a metal cation and shared electrons that surround it.
Metalic Bonds • The cations in metals form lattice that is held in place by metallic bonds and cations and valence electrons. Metal is neutral because the total number of electrons do not change. The more valance electrons there is the stronger the metal.
Explaining properties of metal • The mobility of electrons within a metal lattice explains some of the properties of metal. Metal is a great conductor.
Explaining properties of metal • Metal will not shatter because it is held together by metalic bonds between ions.
Milestones in Metallurgy • The science of metallurgy includes ways to extract metals. In these next couple slides are some examples of advances in metallurgy since 1850
Bessember Converter • 1856 Henry Bessember developed creatid an efficient process for producing steel by blowing air through molten iron.
Empire state building • 1931 this 102 store building was finished. Without steel framed construction this building would be impossible to create.
alloys • Alloy is a mixture of two or more elements, at least one of witch is a metal. Alloys have the characteristic properties of metals.
Copper alloys • Scientists can design alloys with specific properties by varying the types and amounts of elements in an alloy.
Steel alloys • Steel is used in buildings because buildings are big and they need strong metals to hold up the big ole building because its big
Other alloys • Other alloys are mostly used in airplanes, the result is a stronger mateiral and still lighter than metal. The alloys used are aluminum-magnesium alloys.
