PPT-Chemical Bonding in Ionic Compounds

Very Important Going down the periodic table the properties are affected by INCREASING SIZE and INCREASING DISTANCE between the nuclei and the valence es Going across a period properties are affected by the DIFFERING VALENCE NUCLEAR CHARGE and CHARGE ON THE SPECIES. Molecular Geometry. Ch. 6 Sections 1-4 Review. In general, what determines whether atoms will form chemical bonds?. Atoms will form a chemical bond if their potential energy is lowered in doing so.. Describe the difference between ionic and covalent bonding.. Introduction to Chemical Bonding. Introduction to Chemical Bonding. Objectives:. Define . chemical bond.. Explain why most atoms form chemical bonds.. Describe ionic and covalent bonding.. Explain why most chemical bonding is neither purely covalent nor purely ionic.. . Ionic (Atomic) Radii & Coordination Number (CN). Ionic radius: . Hypothetical radius (size) of an ion (. cation. or anion). Calculated values from the bonding distances. CN. Number of one kind of the bond forming ions (atoms) surrounding the other, which are forming the first direct bonding. This topic will be investigated under five main headings:. Chemical Compounds. . Ionic Bonding. . Covalent Bonding. Electronegativity. . Shape of Molecules and Intermolecular forces. Chemical Compounds. SECOND EDITION. Unit 1: ALCHEMY. Matter, Atomic Structure, and Bonding. Lesson 21: Salty Eights. Formulas for Ionic Compounds. ChemCatalyst. Find these cards in . Your Salty Eights . card deck.. 1. List the ionic compounds you can make with pairs of cards, using two different elements.. BOND. ?. The Periodic Table. H. He. Li. Na. K. Be. Mg. Ca. B. Al. C. Si. N. P. O. S. F. Cl. Ne.

Bonding as you’ve never imagined it. http://www.youtube.com/watch?v=BCYrNU-7SfA. Objectives. To consider the features of ionic and covalent bonds, and the compounds they make. 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 . SNC2D – Academic Science. Learning Goals. Use . Lewis dot diagrams to illustrate how a compound forms between a metal and a . non-metal.. Ions are formed when electrons are gained or lost. Where do electrons that are lost go?. Students know . atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or . by exchanging electrons to form ionic bonds. . . . Students know . salt crystals, such as . 3-. 2. Questions for Consideration. How do ionic compounds differ from molecular compounds?. What kinds of ions are in ionic compounds?. What do formulas for ionic compounds represent?. How are ionic compounds named?. Chemical Interactions Occur between the Valence Electrons. Dots. : represent . valence electrons. When atoms combine to make molecules, they form . chemical bonds.. Valence . electron . interaction. When elements combine to form compounds a chemical reaction occurs creating a new compound with properties that are different from the original elements.. When a new compound is formed it has a new chemical formula. A . Section 9.1 – Bonding of Atoms. Ionic and Covalent Bonds. Ionic. : Conduct electricity, high MP, high BP, dissolve in water.  . Covalent. : Do not conduct electricity, low MP, low BP, do not dissolve in water.
