adhesion attraction between unlike molecules
chemical bond an electrical force linking atoms
chemical formula a representation of a substance using symbols for its constituent elements
cohesion the intermolecular force that holds together the molecules in a solid or liquid
covalent bonding a type of chemical bonding that results from the sharing of electron pairs between two atoms
crystalline solid solids in which the particles are arranged in a repeating, 3-D pattern, has a specific melting point
crystal lattice a 3-dimensional geometric arrangement of the atoms or molecules or ions composing a crystal, a 3-dimensional geometric arrangement of the atoms or molecules or ions composing a crystal
diatomic molecule a molecule composed of two atoms
dipole a pair of equal and opposite electric charges or magnetic poles separated by a small distance
dipole-dipole force a force of attraction between polar molecules
double bond a covalent bond in which two pairs of electrons are shared between two atoms
ductile Capable of being drawn out, as into wire or a thread.
electron-dot notation an electron-configuration notation in wich only the valence elctrons of an atom of a particular element are shown, indicated by dots placed around the element's symbol
electronegativity the tendency of an atom or radical to attract electrons in the formation of an ionic bond
hydrogen bonding the force of attraction between a hydrogen molecule with a partial positive charge and another atom or molecule with a partial or full negative charge
hybridization the mixing of two or more atomic orbitals of similar energies on the same atom to produce new orbitals of equal energies
hybrid orbitals orbitals of equal energy produced by the combination of two or more orbitals on the same atom
intermolecular force the force of attraction between molecules
ionic bonding chemical bonding that results from the electrical attraction between cations and anions
lewis structure a formula in which atomic symbols represent nuclei and inner-shell electrons, dot-pairs or dashes between two atomic symbols represent electron pairs in cvalent bonds, and dots adjacent to only one atomic symbol represent unshared electrons
london dispersion forces intermolecular attractions resulting from the constant motion of electrons and the creation of instantaneous dipoles
lone pair chemical bonding that results from the electrical attraction between cations and anions, Pair of electrons associated with one atom in a molecule and not involved in bonding.
malleability the property of a metal that indicates that it can be bent and rolled into sheets
molecule the simplest structural unit of an element or compound
molecular compound a chemical compound whose simplest units are molecules
ionic compound composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal
formula unit the simplest collection of atoms from which an ionic compound's formula can be established
lattice energy the energy relased when one mole of an ionic crystalline compound is formed from gaseous ions
polyatomic ion a charged group of covalently bonded atoms
molecular polarity the uneven distribution of molecular charge
bond energy the energy required to break a chemical bond and form neutral isolated atoms
bond length the average distance between the nuclei of two bonded atoms
molecular formula a chemical formula that shows the number and kinds of atoms in a molecule, but not the arrangement of the atoms.
nonpolar-covalent bond a covalent bond in which the bonding electrons are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge
octet rule States that atoms lose, gain or share electrons in order to acquire a full set of eight valence electrons
orbital a three dimensional region around the nucleus that indicates the probable location of an electron
multiple bond a bond in which the atoms share more than one pair of electrons, such as a double bond or a triple bond.
polar-covalent bond a covalent bond in which the bond ed atoms have an unequal attraction for the shared electons
polar having a pair of equal and opposite charges
resonance the response of a standing wave to another wave of the same frequency.
structural formula an expanded molecular formula showing the arrangement of atoms within the molecule
single bond a covalent bond in which two atoms share one pair of electrons.
surface tension the uneven forces acting on the particles on the surface of a liquid; as if a thin film was stretch across the surface
triple bond a covalent bond in which two atoms share three pairs of electrons
valence electron an electron in the outer shell of an atom which can combine with other atoms to form molecules
Van der Waals forces slight attraction that develops between oppositely charged regions of nearby molecules
VSEPR theory a theory that predicts some molecular shapes based on the idea that pairs of valence electrons surrounding an atom repel each other.
