PPT-Ionic and Covalent Bonding

Including Naming Note We likely wont 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 . 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.. 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. Chapter 9 ~ most compounds, including those in living organisms, are covalently bonded. What You’ll Learn. I will analyze the nature of a covalent bond. I will name covalently bonded groups of atoms. 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). This topic will be investigated under five main headings:. Chemical Compounds. . Ionic Bonding. . Covalent Bonding. Electronegativity. . Shape of Molecules and Intermolecular forces. Chemical Compounds. Ball-and-stick model. Molecular . Compounds. OBJECTIVES:. Distinguish. between the melting points and boiling points of . molecular. compounds and . ionic. compounds.. Molecular . Compounds. OBJECTIVES:. 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. Electrons are transferred from an atom of low electronegativity to one of high electronegativity. Anion (-) and cation ( ) formed. Opposite charges attract – called an . electrostatic force. Formula Unit. Covalent bonds . result from the . sharing . of electrons. between two atoms.. A covalent bond is a . two-electron bond . in which the bonding atoms share valence electrons.. A . molecule . is a discrete group of atoms held together by covalent bonds.. 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 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 . Section 9.1 – Bonding of Atoms. Ionic and Covalent Bonds. Ionic. : Conduct electricity, high MP, high BP, dissolve in water.  . Covalent. : Do not conduct electricity, low MP, low BP, do not dissolve in water. 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..
