Term Definition
octet rule a rule that states that atoms of representative elements form bonds so as to have access to eight electrons
valence electrons an outer s or p electron in the atom of a representative element
lewis dot symbols the representation of an element by its symbol with its valence electrons as dots
lattice a three-dimensional array of ions or molecules in a solid crystal
ionic bond the electrostatic force holding the positive and negative ions together in an ionic compound
covalent bond the force that bonds two atoms together by a shared pair or pairs of electrons
lewis structure the representation of a molecule or ion showing the order and arrangement of the atoms as well as the bonded pairs and unshared electrons of all of the atoms
double bond the sharing of two pairs of electrons between two atoms
triple bond the sharing of three pairs of electrons in a bond between two atoms
resonance structures a lewis structure showing one of two or more possible lewis structures
resonance hybrid the actual structure of the molecule as implied by the resonance structures
allotropes different forms of the same element
electronegativity the ability of an atom of an element to attract electrons to itself in a covalent bond
polar covalent bond a covalent bond that has a partial separation of charge due to the unequal sharing of electrons
dipole two poles- one positive and one negative- that may exist in a bond or molecule
non-polar bond a covalent bond in which electrons are shared equally
VSEPR theory a theory that predicts that electron pairs either unshared or in a bond repel each other to the maximum extent
molecular geometry the geometry of a molecule or ion described by the bonded atoms. it does not include the unshared pairs of electrons.
molecular dipole the combined or net effect of all of the bond dipoles in a molecule as determined by the molecular geometry
