Chapter 6 Chem

mutual electrical attraction between the nuclei and valence electron of different atoms that binds them together

results from sharing of electrons pairs between two atoms

chemical bonding that results from the electrical attraction between cations and anions

a covalent bond in which the bonding electron are shared equally by bonded atoms, resulting in a balanced distribution of electric charge

uneven distribution of charge

covalent bond in which the bonded atoms have an unequal attraction for shared electrons

energy required to break a chemical bond and form neutral isolated atom

average distance between two bonded atoms

indicates the relative numbers of atoms of each kind in a chemical compound by using atomic symbols and numerical subscripts

covalent bond in which 2 pairs of electrons are shared between 2 atoms

electron configuration notation in which only the valence electrons of an atom of a particular element are shown, indicated by dots around the element's symbol

formulas in which atomic symbols represent nuclei and inner shell electrons, dot pairs or dashes between 2 atomic symbols represent electron pairs in covalent bonds and dots adjacent to only one atomic symbol represent unshared electrons

pair of electrons that is not involved in bonding and that belongs exclusivley to one atom

chemical compund whose simplist units are molecules

group atoms that are held together by chemical forces

double or triple bonds

chemical compounds tend to form so that each atom, by gaining, losing, or sharing electrons

bonding in molecules or ions that cant be correctly represented by a single lewis structure

covalent bond where on pair of electrons is shared between two atoms

indicates the kind, number, arrangement, and bonds but not the unchared pairs o atoms in a molecule

covalent bond in which 3 pairs of electrons are shared between 2 atoms

simplest collection of atoms from which an ionic compunds formula can be established

composed of positive and negative ions that are combined so that numbers of positive and negative charges are equal

energy released when one mole of an ionic compound is formed from gaseous ions

an ion made of two or more atoms

substance that can be drawn, pulled, or extrude through a small opening to produce a wire

substance that can be hammered or beaten into thin sheets

the chemical bonding that results from the attraction between metal atoms and surrounding sea of electrons

repulsion between the sets of valence electrons levels and electrons surrounding an atom causes these to be oriented as far apart as possible

mixing of 2 or more atomic orbitals of similar energies on the same atom to produce new hybrid atomic orbitals of equal energies

orbitals of equal energy produced by the combination of two or more orbitals on the same atom

created by equal but opposite charges that are seperated by a short distance

inter molecular force where a hydrogen bonded to a highly elegronegative atom is attracted to an unshared pair of electrons of an electronegative atom in a nearby molecule

intermolecular attractions resulting from the constant motion of electrons and the creation of instantaneous dipoles
