Chapter 8 Flashcards
Molecule
Formed when 2 or more atoms are bonded together
Lewis structure
Shows an arrangement of electrons in a molecule
Sigma bonds
Single covalent bonds (shared electrons centered between 2 atoms)
Pi bond
Formed when parallel orbitals overlap and share electrons
Endothermic reaction
When Greater amount of energy is required to break the existing bondsman the reactants than is released when the new bonds form in the products
Exothermic reaction
Occurs when more energy is released during product bond formation than is required to break bonds in the reactant
Oxyacid
Acid that contains a hydrogen and an oxyanion(1 or more oxygens)
Structural formula
Molecular models
Resonance
condition when more than 1 valid Lewis structure can be made
Coordinate covalent bond
When one atom donates both of the electrons to be shared
VSEPR model
Model used to determine molecular shape
Hybridization
Process which atomic orbitals mix and form new identical hybrid orbitals
Polar covalent bond
Unequal sharing results
Types of molecular shapes
Linear Trigonal planar Tetrahedral Bent Octahedral
Covalent bond
Bond that results from sharing valence electrons
