PPT-IONIC BONDS

Presented By Dr Vatsala Soni Bonding in Solids We have discussed bonding in molecules with three models Lewis Valence Bond MO Theory The above models arent suitable for describing bonding in solids metals ionic compounds. 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.. 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). Valence Electrons and Bonding. The number of valence electrons (electrons in the outermost energy level) in an atom of an element determines many properties of that element, including the ways in which the atom can bond with other atoms.. Covalent bonding. Ionic bonding. Ionic Bonding. 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. Ionic bonds . result when electrons are transferred between atoms. Covalent bonds . result when valence electrons are shared between atoms. Types of Bonds. Formed between a . metal. and a . non-metal. cation. bonds with Bromine.. Write the formula for . . gold(I) sulfide.. In the ionic compound Co. 3. N. 2. ,. which . cation. is present? . . Co (II) or Co (III). Ionic Bonds Containing . Transition Metals. Jennie L. Borders. Standards. SPS1. Students will investigate our current understanding of the atom. b. Compare and contrast ionic and covalent bonds in terms of electron movement.. SPS2. Students will explore the nature of matter, its classification and its system for naming types of matter. is . concerned that he cannot remember all of the important information about the . different types of. chemical bonds, so he asks his . tutor, Josh, . to help him review the different types of chemical bonds prior to choosing his research topic. . Ch. 7 Clicker Review Cations are formed when neutral A. atoms lose electrons B. atoms gain electrons C. atoms gain protons D. atoms lose neutrons ☺ The formula for magnesium oxide is A. MgO B. Mg 2 Bonding. Door. SMARTBOARD. Door. SMARTBOARD. Go to your ASSIGNED seat!!. Go to your ASSIGNED seat!!. Door. SMARTBOARD. CATALYST. Can two anions form an ionic bond? Why or why not?. *Answer in complete sentences!. 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 . SmartStarter. What is the octet rule?. SmartStarter. Draw the electron dot diagram for ionic compound MgCl. 2. Compare. – Eyes on Chemistry. Epsom Salts. Rock Salt. Sucrose. One more…. WHAT DO YOU NOTICE ABOUT THEIR STRUCTURE?. 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 .
