Exam 8: Molecules and Materials

Band gaps tend to be smallest for:

Which of these materials provides an example of a molecular crystalline solid?

The material etched during the creation of a MEMS device is referred to as the:

An addition polymerization must begin with the formation of a(n):

Resonance structures created from monomer units may lead to polymers that:

Additives such as plasticizers are often employed to increase the usefulness of polymers.

Which substance has the lowest vapor pressure:

The ability to bend a metallic solid is described by the metal's:

How many "equivalent" atoms belong to a single body-centered cube unit cell?

Sodium chloride is an excellent example of a(n):

How many "equivalent" atoms belong to a single face-centered cube unit cell?

A useful element for a MEMS device's primary component :

The tendency for molecules with permanent dipoles to align based on those dipoles is known as:

As intermolecular forces of attraction increase for a substance, the molecules tend to separate.

If iridium has a density of 23.3 g/cm³ and forms a face-centered cubic lattice, what is the atomic radius of the iridium atom?

Which term best describes the unoccupied band above the valence band?

Condensation polymers are made using a monomer with two functional groups which split off as the remainder of the two monomers are joined together. Often the small molecule eliminated in the process is water.

Boiling point is achieved when the liquid tranistioning to vapor is in equilibrium with the vapor condensing into liquid.

Semiconductor manufacture involves doping silicon or germanium with controlled trace amounts of another element.

Polymerization involves the linkage of several monomer units.
