AP Chem Chapter 9 Terms Test (11th Unit)

mixing of different types of atomic orbitals to produce a set of equivalent hybrid orbitals

5 bonding domains, 0 nonbonding

type of magnetism that causes a substance with no unpaired electrons to be weakly repelled from a magnetic field

2 bonding domains, 1 or 2 nonbonding

unit of metric measurement equal to 1x10-10m, often used to measure atomic distance, Å

4 bonding domains, 0 nonbonding

theory that accounts for the allowed states for electrons in molecules

5 bonding domains, 1 nonbonding

a model that accounts for the geometric arrangements of shared and unshared electron pairs around a central atom in terms of the repulsions between electron pairs

3 bonding domains, 2 nonbonding

molecular orbital in which electron density s concentrated in the internuclear region, σ and π

4 bonding domains, 2 nonbonding

three electron domains that come off an atom with five total domains with a bond angle of 120°

3 bonding domains, 1 nonbonding

(1⁄2)(MO-MO*)

diagram that shows the energies of molecular orbitals relative to the atomic orbitals from which they are derived

pair of electrons that are shared by two atoms

covalent bond in which electron density is concentrated above and below the line joining the bonded atoms, π bond

model of chemical bonding in which an electron-pair bond is formed between two atoms by the overlap of orbitals on the two atoms

3 bonding domains, 0 nonbonding

an allowed state for an electron in a molecule, MO

property a substance possesses if it contains one or more unpaired electron, will be drawn into a magnetic field

pair of electrons assigned completely to one atom; also called a lone pair

covalent bond in which electron density is concentrated along the internuclear axis, σ bond

6 bonding domains, 0 nonbonding

regions around a central atom where electrons are likely to be found

half the difference of the number of electrons in bonding orbitals and the number of electrons in nonbonding orbitals

4 bonding domains, 1 nonbonding

molecular orbital in which electron density is concentrated outside the region between the two nuclei of bonded atoms, σ* and π*

two electron domains that come off an atom with five total domains with a bond angle of 180°

2 bonding domains, 0 or 3 nonbonding

orbital that results from the mixing of different kinds of atomic orbitals in the same atom
