PPT-Metallic, Ionic and Network Solids

SCH4U1 Mr Dvorsky Ionic Solids Result from the reaction of a metal and a nonmetal Because of the large electronegativity difference electrons transfer from the metallic atom to the nonmetallic atom and the ions that result attract each other . 1 Example: Kis a measure of the extent to which the Example: is 0.022 g/L C. Calculate Convert the solubility mol 103.9)Pb(IO g 557)Pb(IO mol 1L)Pb(IO g0.022 5-232323s 2 Example: is 1.4C. Calc Sugar (Sucrose) Crystals. Table Salt (. NaCl. ) Crystals. Why Draw in Science?. Because you are told to.. Because while you cannot remember the phone number of your family doctor, you can remember how to get to there and which side of the door the door handle is on..

Comparison of Radii. 4. Squashed versus Unsquashed. Left, metallic or covalent radius. Right, Van der Waals radius. Chapter 7. An . ion. is an atom that has gained or lost electrons from the valence shell.. Valence electrons. are the electrons contained in the highest occupied energy level. These electrons will mostly determine the chemical properties of the element. 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..
