Identify and briefly discuss any two properties of steel
structure. Briefly discuss two properties that you have selected
for part a) in the context of a structural steel design.
how does electronegativity relate to the periodic trends of
atomic properties? How does effective nuclear charge, the concept
invoked to understand those trends, also help explain the trends in
electronegativity?
Polymers that have very different applications often have
properties that are very similar. The polymers for soda bottles
(polyethylene), plastic pipes (PVC) and Saran® wrap are all very
different in strength and flexibility. Research the polymer
structure of each of these products and explain how they are
similar on a molecular level. Please no hand written answers and at
least 150 words
