Crystalline lattice Study guides, Class notes & Summaries

Dislocations - a defect in the crystalline lattice. Dislocations move within a structure when stress is applied Pinning - inhibits the dislocation from moving within the structure resulting in the metal becoming stronger and more brittle. Precipitates - small atoms that fit within the vacant spaces between base metal atoms Entanglements - grains of a structure becoming stretched out. Created by cold working Tensile strength - A measure of how much stress from pulling, or tension, a materia...

Chemical Bonding and Nomenclature Exam 2023-2024 chemical bonding - Answer-The combining of atoms to form molecules or ionic compounds ionic bond - Answer-A chemical bond resulting from the attraction between oppositely charged ions. ionic compound - Answer-Composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal valence electrons - Answer-The electrons in the outermost shell (main energy level) of an atom; these are the...
