100
The force of attraction between molecules. This is not a bond.
What is an intermolecular force?
100
A ratio derived from the equlaity between two different units that can be used to convert from one unit to the other.
What is a conversion factor?
100
An arrangement of the elements in order of their atomic numbers so that elements with similar properties fall in the same column or group.
What is the periodic table of elements?
100
The repulsion between teh sets of valence-level electrons surrounding an atom causes these sets to be oriented as far apart as possible.
What is VSEPR theory?
100
Short range proton-neutron, proton-proton, or neutron-neutron force that holds the nucleus together.
What are nuclear forces?
200
An intermolecular attraction resulting form the constant motion of electrons and the creation of instantaneous dipoles.
What is London dispersion force?
200
The number of particles in exactly one mole of a pure substance.
What is Avogadro's number?
200
Physical and chemical properties of the elements are periodic functions of their atomic numbers.
What is periodic law?
200
The maximum amount of product that can be produced from a given amount of reactant.
What is the theoretical yield?
200
A formula in which atomic symbols represent nuclie and inner shell electrons, dot pairs,or dashes between two atomic symbols represent electron pairs in covalent bonds, and dots adjacent to only one atomic symbol represent unshared electron.
What are Lewis structures?
300
Equal but opposite charges that are separated by a short distance.
What is a dipole?
300
A small whole number that appears in front of a formula in a chemical equation.
What is a coefficient?
300
An electron that is available to be lost, gained, or shared in the formation of chemical compounds.
What are valence electrons?
300
The bonding in molecules or ions that cannot be correctly represented by a single Lewis structure.
What is resonance?
300
The energy released when one mole of an ionic crystal is formed from gaseous ions.
What is lattice energy?
400
The mixing of two or more atomic orbitals of similar energies on the same atom to produce new orbitals of equal energy.
What is hybridization?
400
A representation, with symbols and formulas, of the identities and relative amounts of the reactant and products in a chemical reaction.
What is a chemical equation?
400
Chemical compounds tend to form so that each atom, by gaining, losing, or sharing electrons, has an octet of electrons among the bonded atoms.
What is the octet rule?
400
A solid that is produced as a result of a chemical reaction in solution and that separates from the solution.
What is a precipitate?
400
Orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron, and all electrons in singly occupied orbitals must have the same spin.
What is Hund's rule?
500
The intermolecular force in which a hydrogen atom that is bonded to a highly electronegative atoms is attracted to an unshared pair of electrons of an electronegative atom in a nearby molecule.
What is hydrogen bonding?
500
Calculations involving the mass relationships between reactant and products in a chemical reaction.
What is reaction stoichiometry?
500
A measure of the ability of an atom in a chemical compound to attract electrons.
What is electronegativity?
500
The percentage by mass of each element in a compound.
What is percentage composition?
500
The arrangement of electrons in an atom.
What is electron configuration?
