PPT-Covalent Bonds The joy of sharing!

Covalent Bonds Covalent bonds occur between two or more nonmetals electrons are shared not transferred as in ionic bonds The result of sharing electrons is that atoms attain a more stable electron configuration. Unit 1 – Chemical Changes and Structure. Bonding and Structure. The Formation of Bonds. Bonds. are . electrostatic forces. (attractions between positive and negative charges) which hold atoms together.. 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.. 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.. 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). 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.. Describe . ionic bonding. in 1 complete sentence.. Describe . covalent bonding. in 1 complete sentence.. Polar. Nonpolar. nonpolar covalent bond. :. nonpolar covalent bond. : . atoms with equal pull (similar electronegativity) so bonding . 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 . 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. 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. When elements combine to form compounds a chemical reaction occurs creating a new compound with properties that are different from the original elements.. When a new compound is formed it has a new chemical formula. A . 6.2. Molecules. Molecules – a neutral group of atoms held together by . covalent. bonds. Molecular compound – a . cmpd. whose simplest units are molecules. Chemical formula – indicates relative # of atoms of each kind in a chemical compound by using atomic symbols & subscripts. Bioc. . 201. بسم الله الرحمن الرحيم. 1. What is Biochemistry?. Simplest definition: . “Chemistry of the living cell”. Uses basic laws of . chemistry. and . biology. to explain processes of living cells..
