PPT-More Covalent Bonding

Coordinate Covalent Bonds and Resonance Structures Chemistry 11 Ms McGrath Coordinate Covalent Bonds A covalent bond is formed by two atoms sharing a pair of electrons The atoms are held together because the bonding electron pair is attracted by both of the nuclei. 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.. 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.. . Ionic (Atomic) Radii & Coordination Number (CN). Ionic radius: . Hypothetical radius (size) of an ion (. cation. or anion). Calculated values from the bonding distances. CN. Number of one kind of the bond forming ions (atoms) surrounding the other, which are forming the first direct bonding. IB Topics 4 & 14. Text:. Ch 8 (all except sections 4,5 & 8). Ch 9.1 & 9.5.

Chemical Bond. PART 5: Giant Covalent Structures, Metallic Bonding & Physical Properties. 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 . 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 .
