Formula mass: a molecule is the sum of the atomic weights of the atoms in the empirical formula of the compound.
Molecular mass: A number equal to the sum of the atomic masses of the atoms in a molecule. The molecular mass gives the mass of a molecule relative to that of the atom, which is taken to have a mass of 12.
Avogadroa number: The number of atoms, molecules or particles found in exactly 1 mole of substance.
Molar mass: The mass of one mole of a substance, usually expressed in grams or kilograms.
Mole: A chemical mass unit, defined to be molecules, atoms, or some other unit. The mass of a mole is the gram formula mass of a substance.
Percent composition: percentage by mass of each element in a compound
Molecular formula: An expression which states the number and type of atoms present in a molecule of a substance.
bond energy: The amount of energy necessary to break one mole of bonds of a given kind (in gas phase).
bond length: The equilibrium distance between the nuclei of two groups or atoms that are bonded to each other.
coordinate covalent bond: Covalent bond in which both shared electrons are furnished by the same species; bond between a Lewis aced and Lewis base.
covalent bond: Chemical bond formed by the sharing of one or more electron pairs between two atoms.
double bond: A bond where two electron pairs are shared between two atoms.
pi bond: is a covalent bond formed between two neighboring atom’s unbounded p-orbitals.
resonance: used to explain properties of the octet rule when a single Lewis structure is inadequate.
sigma bond: bonds resulting from the head-on overlap of atomic orbitals, in which the region of electron sharing is along and symmetrical to the imaginary line connecting the bonded atoms.
triple bond: is three electron pairs which are shared between two bonded atoms.
electron promotion: A statement describing the populations of electronic energy sublevels of an atom.
orbital hybridization: Orbital formed by the combination of two or more atomic orbitals.
polar covalent bonds: A bond in which a pair of electrons are shared in common between two atoms, but the pair is held more closely by one of the atoms.
polyatomic ion: is an ion comprised of two or more atoms.
ionic bond: Is a chemical link between two atoms caused by the electrostatic force between oppositely-charged ions in an ionic compound.
octet rule: Many representative elements attain at least a share of eight electrons in their valence shells when they form molecular or ionic compounds; there are some limitations.
