<p>Name: HONORS CHEMISTRY – SOLID STATE http://chemistry.about.com/od/matter/a/Types-Of-Solids.htm</p><p>Two types of solids in broadest terms:</p><p>1. ______Define:</p><p>2. ______Define:</p><p>Crystals are made of unit cells. A unit cell is the “smallest unit that the crystal can be divided into.” Like Lego blocks that assemble to make a castle, each individual block is a unit cell.</p><p>The crystal lattice and unit cell of a crystal of sodium chloride. Sodium ions, Na+, are the smaller spheres, Chloride ions, Cl–, are the larger spheres. (a) Overall crystal lattice; (b) unit cell; (c) unit cell, showing division of spheres.</p><p>Basic Unit Cell Shapes: The shape of the unit cell reflects the shape of the overall crystal. Four Types of Crystalline Solids Fill out the chart below:</p><p>Type of Particles Force(s) Properties (3-4) Examples Crystalline Found at unit holding crystal Solid cell positions together</p><p>Ex: Molecular Atoms or Intermolecular Low melting Points, Water (Ice), Solid Molecules Forces soft solids, brittle, Sugar nonconductors of (Sucrose) heat and electricity,</p><p>Ionic solids</p><p>Metallic solids</p><p>Covalent Network (atomic) solids Classify the compounds below:</p><p>Compound Type of Crystalline Solid</p><p>NaC2H3O2</p><p>Li</p><p>O2</p><p>CO</p><p>SiO2</p><p>Mg(OH)2</p><p>AlCl3</p><p>C (diamond)</p><p>Question: Watch the video https://www.youtube.com/watch?v=kypne21A0R4 and answer question below: If atoms are mostly empty space, how can there be solids?
