Virtual and tactile molecular models: Their complimentary nature in Discovery-based general chemistry Scott A. Sinex and Barbara A. Gage Prince George’s.
Chapter 9 Molecular Geometry and Bonding Theories.
Molecular geometry – the orientation of atoms in space (how the atoms are arranged in a molecule) VSEPR Theory – Valence Shell Electron Pair Repulsion.
Ch 6.5 Molecular Geometry. VSEPR Theory Use VSEPR theory Valence-Shell-Electron-Pair Repulsion =the repulsion between electron pairs causes molecular.
Drawing Lewis structures 1.Calculate the total number of valence electrons in the compound. 2.Choose the central atom and place the remaining atoms symmetrically.
Lecture 3111/18/05. Electron Pair Geometries Molecules with only single covalent bonds around central atom. Axial atomsEquatorial atoms.
1 For ions we must adjust the number of electrons available, A: Add one e - to A for each negative charge Subtract one e - from A for each positive charge.
Significant Figures – start at the left and proceed to the right 1.If the number does not have a decimal point count until there are no more non zero numbers.

Chapter 9 Molecular Geometry. Introduction 1.Lewis Structures help us understand the compositions of molecules & their covalent bonds, but not their overall.
