Increase your spatial skills and awareness using software designed by the CCDC. 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.. 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 . 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.

A chemical bond is an attraction between atoms brought about by:. 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. 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. 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.. Do . Now: Identify . Bond Type from Formula. Au. Ag. CO. 2. Li. 3. N. Na. 2. S. Mg. CsF. H. 2. O. NaCl. SO. 2. Cu. CH. 4.

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. 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..
