PPT-Unit 5B: Covalent

Unit 5B Covalent Bonding Covalent Bonds 2 nonmetals atoms share e to get a full valence shell C 1s 2 2s 2 2p 2 F 1s 2 2s 2 2p 5 Both need 8 ve for a full outer shell . The ions are arranged in a lattice. There is attractive electrostatic forces between the ions which are very strong e.g. sodium chloride ionic lattices. . Give two properties of giant ionic structures. . Ch. . 16. Covalent Compounds. Covalent bonds. form when atoms share . their valence electrons. .. Covalent compounds. are formed from 2 or more nonmetals.. Rules for Naming Covalent Compounds. 1. Prefixes are used to show how many atoms of each element are present in the compound . Why do atoms bond?. Atoms gain stability when they share electrons and form covalent bonds.. Lower energy states make an atom more stable.. Gaining or losing electrons makes atoms more stable by forming ions with noble-gas electron configurations.. VSEPR Theory, Polarity, and using . Electronegativity. Covalent . Bonds. Forms when 2 atoms share a pair of valence e. -. A. Types of Covalent Bonds. 1. . Single Covalent Bond . – two atoms share . 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. 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). . 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 . Bonding. Bonding models for methane, CH. 4. . Models are NOT reality. Each has its own strengths and limitations.. Ga . 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.. 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. Types of bonds. Ionic bonding. results from electrostatic attractions among ions, which are formed by the . transfer. of one or more electrons from one atom to another.. Covalent bonding. results from . Mrs. Page. Essential Idea. Lewis (electron dot) structures show the electron domains in the valence shell and are used to predict molecular shape. .. Nature of Science. Scientists . use models as representatives of the real world – the development of the model of molecular shapes (VSEPR) to explain observable properties.. Covalent Bonding. A . chemical bond . is the force that holds two atoms together and makes them function as a unit. Atoms form bonds to become most stable and obtain an octet. Covalent Bonding: Electrons are shared between two or more elements. Always between 2 non-metals. 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 1: . Ionic & Covalent Bonding. Chemical Bonds. A chemical bond is an attraction between 2 atoms or ions..
