Term
Formula Unit
Definition
The simplist collection of atoms from an ionic compound's formula can be established
Term
ionic compound
Definition
a compound composed of positive and negative ions that are combined so that the positive and negative charges are equal
Term
Lattice Energy
Definition
the energy released when one mole of an ionic crystalline compound is formed from gaseous ions.
Term
Polyatomic ion
Definition
a charged group of covalently bonded atoms
Term
ductility
Definition
the ability of a substance to be drawn, pulled, or extruded through a small opening to produce a wire
Term
Malleability
Definition
the ability of a substance to be hammered or beaten into thin sheets
Term
Metallic bonding
Definition
Chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons
Term
dipole
Definition
equal but opposite charges by a short distance
Term
dipole-dipole force
Definition
a force of attraction between polar molecules
Term
Metalic Bonding
Definition
Chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons
Term
Hybrid Orbital
Definition
orbitals of equal energy produced by the combination of two or more orbitals on the same atom
Term
Hybridization
Definition
the mixing of two or more atomic orbitals of simialr energies on the same atom to produce new orbitals or equal energies
Term
Hydrogen Bonding
Definition
the intermolecular force in which a hydrogen atom that is bonded to a highly electronegative atom is attracted to an unshaired pair of electrons of an electronegative atom in a nearby molecule
Term
intermolecular force
Definition
the force of attraction between molecules
Term
London dispersion force
Definition
an intermoleculer attraction resulting from the constant motion of electrons and the creation of istantaneuous dipoles
Term
molecular polority
Definition
the uneven distribution of molecular charge
Term
VSESPR theory
Definition
repulsion between the sets of of valence level electrons surrounding an atom causes these sets to be oriented as far apart as possible
