Mettalic bonding (Properties of alloys in terms of non directional bonding…
Mettalic bonding
-
Alloys
Mixture consistent of two or more metals combined with an alloying element made by one or more non metals.
-
Example
brass= Copper and Zinc, used on door handles, window fittings, screws
Properties
Electrical Conductivity
Metals are conductors because of the delocalized electrons which move freely through the lattice thus creating current
Malleability
Due to the sea of electrons and the fact that the bonds in metal do not have a direction the cations can slide past each other allowing an object to rearrange and change its shape.
Trends in melting points
-
Group metals increase the ionic radius as their atomic number increases thus decreasing the melting point
Metallic bond
Electrostatic attraction where the negative charges are delocalized electrons and positive charges is a lattice of cations
