CHAPTER 12: SOLIDS AND MODERN MATERIALS

solid solution

When atoms of the solute in a(n) ________ occupy positions normally occupied by a solvent atom.

mutual electrostatic attraction

Are held together by the ________ between cations and anions.

geometrical pattern of points

The ________ on which the unit cells are arranged.

irreversible chemical

(Also called a thermoset) is shaped through ________ processes and, therefore, can not be reshaped readily.

polymeric solids

Are ________ that can be formed into various shapes, usually by the application of heat and pressure.

electrical conductivity

Doping provides an opportunity for controlling the ________ through precise control of the type and concentration of dopants.

Jöns Jakob Berzelius

In 1827 ________ coined the word polymer (from the Greek polys,"many, "and meros, "parts) "to denote molecular substances of high molecular weight formed by the polymerization (joining together) of monomers, molecules with low molecular weight.

electrostatic attraction

Are held together by the ________ between cations and anions: ionic bonds.

covalent bonds

Because ________ are much stronger than intermolecular forces, these solids are much harder and have higher melting points than molecular solids.

material

Which is a(n) ________ that exhibits rubbery or elastic behavior.

Amorphous solids

________ do not have the well- defined faces and shapes of a crystal.

interstitial positions

When the solute atoms occupy ________ in the "holes "between solvent atoms.

Solids

________ in which atoms are arranged in an orderly repeating pattern.

Atomic orbitals

________ combine to make molecular orbitals that can extend over the entire molecule.
