CHM 114 Study Guide - Midterm Guide: Reagent, Electronvolt, Triclinic Crystal System
Document Summary
Amorphous solids lack any consistent order to their arrangement. Crystalline solids are the result of a repeating array of systematically arranged atoms. Held together by delocalized sea of valence electrons. Low electronegativity of metal nuclei allows electrons to move around freely. Solids held together by the electrostatic attraction between positively charged cations and negatively charged anions. Solids which are held together by an extensive network of covalent bonds. Solids composed of molecules held together by molecular forces. Long chains of atoms (typically carbon) where there is repeating arrangement of atoms known as a monomer, which is repeating throughout the molecule. Solids which have a size of less than 100nm and where the bulk properties of a material begin to change. One can deduce the pattern in a crystalline solid by thinking of the substance as a lattice of repeating shape formed by the atoms in the crystal.
