exam 3 Flashcards
Anion –
Atom in a molecule that gains an electron through bonding
Cation –
Atom in a molecule that loses an electron through bonding
Frenkel Defect –
A cation vacancy paired with a cation interstitial (could also describe
anion, but it is rarer for anions)
Schottky Defect –
A cation vacancy paired with an anion vacancy
Stoichiometry –
Describes the ratio of anions to cations in a crystal structure
Viscosity –
Measure of a glassy material’s resistance to deformation
Polymer –
Large chain of repeating units with same chemical makeup
Mer –
Single unit of polymer
Monomer –
A mer that exists on its own
Isomer –
A molecule with the same chemical formula but different arrangement
Copolymer –
Polymer with more than one type of mer
Thermoplastic –
Polymer can break apart during heating
Thermosetting –
Polymer is permanently set upon cooldown
Elastomer –
Totally elastic type of polymer
Particle Reinforced –
Large particles in a matrix
Fiber Reinforced –
Long fibers in a matrix
Cement –
Ceramic that mixes with water then hardens
Concrete –
Composite made with cement, sand, gravel, water
Oxidation –
Element gives up electron
Reduction –
Element gains electron
Anode –
Metal where oxidation occurs
Cathode –
Metal where reduction occurs
