Chapter 7 Covalent Bonds and Molecular Architecture

Chapter 7 Covalent Bonds and Molecular Architecture. Octet rule: Main group elements tend to undergo reactions that leaves them with either 2 or 8 electrons in their outer or valence shell achieved by sharing electrons.

Chapter 13 Structure and Shape

Chapter 13 Structure and Shape. Drawing Lewis Diagrams. 1 Count the total number of valence electrons. If the species is an ion, the number of valence electrons must be adjusted for the charge on the ion. Determine the number of electron pairs.

Molecular Geometry

Molecular Geometry. Notes 2. Molecules with Expanded Valence Shells. Atoms that have expanded octets have AB 5 (trigonal bi- pyramidal or AB 6 octahedral, electron domain geometries. Trigonal bipyramidal structures have a plane containing three electron pairs

When does the octet rule fail?

When does the octet rule fail?. H, He and Li. Helium strives for 2 valence electrons 1s 2 configuration Hydrogen will sometimes will share its one electron with another atom, forming a single covalent bond Lithium will lose its lone valence electron, gaining the 1s 2 configuration of He.
