PPT-Covalent bonding and Sterio

hemistry VSEPR Theory According to the valence shell electron pair repulsion theory VSEPR theory the geometry of a covalent compound depends upon the number and arrangement in the space of electron pairs present in the valence shell of the central atom This number is half of the summation of electrons present in the valence shell of the central atom and the electrons contributed by the combining atoms Thus in the case of H. 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.

To consider the features of ionic and covalent bonds, and the compounds they make. 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..
