PPT-Chapter 12 Solids and Modern Materials

Lecture Presentation Classifying Solids Based on Bonds Metallic solids are held together by a sea of collectively shared electrons Ionic solids are sets of cations and anions mutually attracted to one another. In Perspective. Symmetry and Regularity. Objects that are symmetrical look the same from several different views, or two sides are mirror images of each other.. Symmetric solids are referred to as regular, or Platonic solids.. -Describe . these objects-. What are some things that you notice?. Have you ever seen anything like these? Where?. What do they remind you of?. How would you describe these objects?. How can we describe these using geometric terms?. By Myre and William. Gasses. Gasses are particles that float from earth to the . atmosphere and its particles go around to fill every place in a container and when the . they are open they will go to every space around.. Liquids. Objectives. Identify and explain the properties of liquids according to the Kinetic Molecular Theory. Describe the process in which liquids turn to gases.. Describe the process in which liquids turn to solids. ● . Phases and Phase Diagrams. ● Liquids and Liquid Properties. ● Intermolecular Forces. ● Heating Curves. ● Introduction to Solids. ● Cubic Packing Arrangements. ● Closest-Packed Structures. By. Sidra Jabeen. Department of Chemical Engineering,. University of Engineering & Technology Lahore . Intermingling of two or more separate components to form more or less uniform product. . Some other terms are. By the end of the lesson you should know. The names of the states of matter. That matter is made of particles. How the particles are arranged in solids liquids . and gases. The names of the changes of state. All . faces, all edges, all corners, are the . same.. They are . composed . of . regular 2D polygons:. There were infinitely many 2D n-. gons. !. How many of these regular 3D solids are there?. Making a Corner for a Platonic . SCH4U1. Mr. . Dvorsky. Ionic Solids. Result from the reaction of a metal and a non-metal. Because of the large . electronegativity. difference, electrons transfer from the metallic atom to the non-metallic atom and the ions that result attract each other. . How materials work.
