equally likely structures of a molecule
free radicals
unpaired electrons
formal charge
the valence electrons of an element minus the electrons allocated to it in the lewis structure

the ability of an atom to attract electrons
dipole moments
the difference of electronegativity between two atoms in a covalent bond
symmetrical molecules are usually ____
nonpolar
asymmetrical molecules are usually ____
polar
bond order
the average amount of bonds that an atom can make
bonding domain
region where bonding occurs
nonbonding domain
region designated for lone pairs
derived structure
when a nonbonding pair is in a bonding region
valence electron theory
covalent bonds overlap orbitals where bonding occurs and the spin is opposite
molecular orbital theory
molecules are similar to atoms because the both have a charge and distinct energy levels where electrons are

single bond
sigma and pi bond
double bonds
sigma and two pi bonds
