PPT-Chapter 7 – Ionic and Metallic Bonding

Augustine Section 71 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 . 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. Co = Together. The Octet Rule. The octet rule says that all atoms want to have eight valence electrons, like the noble gases.. One way that atoms can follow the octet rule is by giving and taking electrons… ionic bonding. 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 . Metals. Look at the Periodic Table…. 75% of elements are metals!. Metals. They can vary a lot…. General Properties of Metals. Dense. Malleable. Ductile. Good conductors of heat and electricity. Shiny Lustre. 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.. . 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. 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.

CA Standards. Students know . atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds. . Metallic Bonding. The chemical bonding that results from the attraction between metal . 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?. Net ionic equations are useful in that they show only those chemical species directly . participating in . a chemical . reaction. The keys to being . able to . write net ionic equations are the ability to recognize monatomic and polyatomic ions, . Group. Valence. electrons. General electron configuration.
