PPT-Ionic Bonding

Specification Candidates should be able to a describe the term ionic bonding as electrostatic attraction between oppositely charged ions b construct dotandcross diagrams to describe ionic 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 w/Transition. Metals. Ionic w/ Polyatomic. Covalent. Writing. Formula from Name. Write out ions, . criss. cross number. of charge to make subscripts, reduce. Write out ions, . criss. cross number. Aqueous solutions of Sodium Hydroxide and Copper (II) Chloride combine to form an aqueous solution of . sodium. . chloride and . solid blue Copper Hydroxide . Write a skeleton equation. Balance the equation.. Including Naming. Note: We likely won’t make it to covalent nomenclature, this is the one students find FAR easier than ionic. Please refer to the videos and naming hand out for help with this, and as always office hours, discussions, and . Chapter 4.10,4.11 and 5. Combining Elements. When we begin combining elements we make compounds.. Two types. Non-metal and metal. Non-metal and non-metal. Each type has unique physical and chemical properties. . and Structure. IB Chemistry. Topic 4. . Bond - A force that holds . atoms . together and . makes . them . function as a . unit.. 4.1 Ionic Bonding. An . ion. is a charged particle. Ions form from atoms or from groups of atoms by . Very Important!. Going down the periodic table the properties are affected by INCREASING SIZE and INCREASING DISTANCE between the nuclei and the valence . e-s. Going across a period, properties are affected by the DIFFERING VALENCE, NUCLEAR CHARGE and CHARGE ON THE SPECIES. Na. +. Al. 3+. S. 2–. 2Ca. 2+. PO. 4. 3–. 3Cl. –. Review: forming ions. Ionic (i.e. salt) refers to +ve ion plus -ve ion. Usually this is a metal + non-metal or metal + polyatomic ion (e.g. NaCl, NaClO. 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. 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 . 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. 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 . Michael. Tian. Koya. Ionic Bonding. Definition: . The complete transfer of valence electron(s) between atoms. It’s a type of chemical bond that creates two oppositely charged ions. Typically an ionic bond happens between a metal and a non-metal, where the metal loses electrons to the non-metal, resulting in a cation and a anion.. Ionic bonds form a . giant lattice structure. Sodium chloride is an ionic compound formed by the reaction between the metal sodium and the non-metal chlorine.. During the reaction, one electron is transferred from each sodium atom to each chlorine atom..
