PPT-Ionic and Metallic Bonding

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. and . Electronegativity. Presented by . Leticia Bonita Prince. Newcastle University 4. th. Year . MChem. Student. Aims of Today. Increase your understanding of bonding and electronegativity. Increase your spatial skills and awareness using software designed by the CCDC. 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. IB Topics 4 & 14. Text:. Ch 8 (all except sections 4,5 & 8). Ch 9.1 & 9.5. Ch 10.1-10.7. My Name is Bond. Chemical Bond. PART 5: Giant Covalent Structures, Metallic Bonding & Physical Properties. 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.

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.. Augustine. Section 7.1 - Ions.
