A description of alloy has to be given. The structural differences between substituted alloys and interstitial alloys have to be explained. Example for both the type of alloys has to be cited. Concept introduction: An alloy is a mixture of metals or metals with non-metals . The so formed alloy exhibit excellent properties like durability and finds various applications. Example : Bell metal is an alloy made of 77% copper and 23% Tin. There are two types of alloys - substitutional alloy and interstitial alloy. In substituted alloys, one type of metal atoms occupies the lattice sites of the other metal atom. In interstitial alloys, one type of metal atoms occupies the interstitial spaces in the lattice of another metal.

How close are the Mulliken and Pauling electronegativity scales? (a) Now that the ionization energies and electron affinities have been defined, calculate the Mulliken and Pauling electronegativities for C, N, O and F. Compare them. (Make the necessary adjustments to the values, such as dividing the ionization energies and electron affinities by 230kj/mol) (b) Plot both sets of electronegativities against atomic number (use the same graph). (c) Which scale depends most consistently on position in the Periodic Table?
