Chapter 10 Key Terms Flashcards
(25 cards)
Antibonding orbital
Molecular orbital higher in energy than orbitals that formed it
Bond order
((bonding e-)-(antibonding e-))/2
Bonding orbital
Orbital lower in energy than those which formed it
Diamagnetic
State of an atom with only paired electrons
Electron geometry
Geometrical arrangement of electron groups in molecule
Electron groups
Term for lone pairs, single bonds, lone electrons, or multi bonds
Hybrid orbitals
Orbitals formed from combination of normal orbitals to allow bonds
Hybridization
Combining standard orbitals to allow for bonding orbitals
Linear Geometry
When there are three atoms and 180* angle between them
Molecular geometry
Shape of atoms in a molecule
Molecular orbital theory
Model of bonding saying electrons are delocalized, orbit whole molecule
Nonbonding orbital
Orbital with localized electrons
Octahedral arrangement
seven electron groups together, 90* angles
Pi bond
Bond forming between second or third bond in multiple bond
Seesaw
Molecular geometry of trigonal bipyramydal molecule with with one lone pair
Sigma bond
All single bonds and first bond in multi bond
Square planar
Geometry of octahedral molecule with two lone pairs
Square Pyramidal
Geometry of trigonal bipyramydal molecule with one lone pair
T shape
trigonal bipyramydal molecule with two lone pairs
Tetrahedral geometry
Five electron groups.
trigonal bipyramydal
Six atoms together
Trigonal planar
Four atoms in a plane
Trigonal pyramidal
Tetrahedral electron groups with one one lone pair
Valence bond theory
model of bonding that says bonding electrons occupy altered but localized orbitals
