You will find an example of a sound and unsound deductive argument here.

http://knowled.co.uk/59985?q=deductive%20argument

A sound deductive argument would be:

All squares are rectangles.

A rectangle has four sides.

All squares have four sides.

 

This is sound because the definition of a square and rectangle both include that element of four sides.

An unsound argument would be:

All toads are cold-blooded.

All reptiles are cold-blooded.

All toads are reptiles.

In this case, toads and reptiles do share the same characteristics, but a toad is not a reptile.  It is an amphibian.
