WHY ARE FACE-CENTERED CUBIC METALS MORE DUCTIC, BETTER CONDUCTORS OF HEAT AND ELECTRICITY COMPARED TO BODY-CENTERED CUBICS?
Copper is a typical face-centered-cubic metal. In its pure state, it has extremely high electrical conductivity. Oxygen in copper causes a major reduction of conductivity. To investigate this issue further, I want to you to tell me whether oxygen atoms substitute for copper atoms, or if they enter interstitial sites.

Compute the resistance over the entire 60 mm of the specimen using the data in (i).
fill in the blanks When an element has its proper complement of valence electrons, it is electrically _________; when an atom has more or fewer than that number, it is an ion and has an electric charge. The charge is ________ when extra electrons are present and ________ when some are missing. .The ____________ bond is formed among metallic atoms when some electrons in the valence shell separate from their orbital path and exist in a free state like a cloud or gas. Surrounding the positive nuclei in this highly mobile state, the negative cloud bonds the atoms together. Because the electrons in the cloud do not “belong” to any particular atoms, the bond strengths can vary, deformation can take place without rupture, and good heat and electrical conductivity can occur owing to the easy movement of electrons from one atomic site to the next. This type of bonding makes possible some of the useful characteristics of metals, both mechanical properties and physical properties.
