What is a Lewis structure?
A 3D structure showing valance electrons
A 2D structure showing valance electrons
A 2D structure showing electrons in a covalently bonded molecule
A 3D structure showing electrons in a covalently bonded molecule

What does a dash represent in a Lewis structure?
Single electrons
The bonding pair of electrons between two atoms
A double bond
One electron bonding two atoms
What do the electrons shared in a covalent bond "count" toward?
The number of bonds between atoms
The octet for one of the atoms
The octet for both atoms they are between
The number of atoms bonded in a molecule
What is the first step of drawing a Lewis electron-dot structure?
(a)
Name one reason a molecule or polyatomic ion would be an exception to the octet rule.
Molecules with incomplete octets
Molecules with an odd # of electrons
Molecules with expanded octets
All the above
What are resonance structures?
A mirror image of a structure
A bond and a half
A different way to draw a molecular structure
A pain in the neck
What is a formal charge
(a)
What is the VESPR theory?
Valence electrons around a central atom stay as far apart as possible to minimize the repulsions
Valence electrons around a main atom stay as far apart as possible to maximize the repulsions
Valence electrons around a central atom stay as close together as possible to minimize the repulsions
Valence electrons around a main atom stay as close together as possible to maximize the repulsions
Trigonal planar
Tetrahedral
Trigonal pyramidal
Trigonal bipyramidal
