PPT-Unit 3: Ionic and Metallic Substances Review

Honors Chemistry 1 Which of the following is ionic NF 3 HCl CuCl 2 CO 2 2 Which of the following is covalent MgO H 3 N FeO ZnCl 3 To form an ion Nitrogen will Lose 3 electrons to become N. 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.. COVALENT BOND. bond. formed by the . sharing . of . electrons . Covalent . Bonds. Between nonmetallic elements of similar electronegativity. .. Electronegativity = how badly an atom wants to add an electron (non metals have higher electronegativity). Solids. Crystalline Solids- have a regular repeating arrangement of their particles.. Salts, Sugars, Metals. Amorphous Solids- have no regular repeating arrangement of their molecules. Common glass, several polymers.. Bonding Discussion. Bonding. . Ionic. . Covalent. . Metallic. Determined by difference in Electronegativity between atoms.. Ionic . Compounds. Crystalline . solids (made of ions) . High melting and boiling points . 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. . Endo vs Exo Reaction INQUIRY . Solution Process Model . Solute particle separate (endo). Solvent particles separate (endo) . Solute and Solvent particles combine (. exo. ) . Electrolytes. Electrolytes conduct electricity!. Electrons are transferred from an atom of low electronegativity to one of high electronegativity. Anion (-) and cation ( ) formed. Opposite charges attract – called an . electrostatic force. Formula Unit. Fall, 2017. 2. X-ray Diffraction Image. Images like these can be used to determine crystal structures. 3. 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. th. Grade Science. What are “Substances”? . Substances can be identified as either…. Elements. Compounds. Mixtures. So, what is a substance?. A substance cannot be further broken down or . p. urified by physical means.. Day . 6. – Venn Diagram, . haber. Process. Metallic . Bonding, Properties of Substances reading, . Warm up. ON PAGE 23. What do ionic and covalent bonding have in common? What is different?. Time: . Augustine. Section 7.1 - Ions. Valence electrons. are the electrons in the . highest. occupied energy level.. Valence electrons. are the only electrons involved in . chemical bonding. .. Elements in the same . Salts, Sugars, Metals. Amorphous Solids- have no regular repeating arrangement of their molecules. Common glass, several polymers.. Crystalline Structure. Amorphous. Amorphous solids. Amorphous solids, due to a lack of arrangement of molecules, . Group. Valence. electrons.
