67235138StrongerBigger charges mean (stronger/weaker) bonds
67235139WeakerCharges farther apart mean (stronger/weaker) bonds
67235140HighSubstances held together by ionic bonds have (high/low) melting and boiling points
67235141Electrons are localized around a particular atom (so electrons don't move around lattice)Why are ionic solids poor conductors of electricity?
67235142TrueIonic liquids conduct electricity - True or False?
67235143Ionic bondsWhat are salts held together by?
67235144DipoleWhen a non-ionic bond has one side pulling on the electrons more strongly than the other side
67235145H - 2; Be - 4; B - 6Exceptions to the Octet Rule
67235146dIn molecules with "-" subshells available, the central atom can have over 8 valence electrons
67235147NO, NO2Two molecules with odd number of electrons
67235148Repulsive strengthLone pairs occupy little more space than bonded pairs because lone pairs have a higher --------- ------- than bonding pairs
67235149Trigonal planar, bentVSPER shape with 3 electron pairs on central atom (0, 1 lone pairs)
67235150Tetrahedral, trigonal pyramidal, bentVSPER shape with 4 electron pairs on central atom (0, 1, 2 lone pairs)
67235151Trigonal bipyramidal, see-saw, T-shaped, linearVSPER shape with 5 electron pairs on central atom (0, 1, 2, 3 lone pairs)
67235152Octahedral, square pyramidal, square planarVSPER shape with 6 electron pairs on central atom (0, 1, 2 lone pairs)
67237151CovalentlyIntermolecular forces only exist within ---------- bonded molecules
67237152Network solidAtoms are held together in a lattice of covalent bonds in this type of solid
67237153LocalizedMetallic solids are good conductors of heat and electricity because its electrons are ---------
67237154London dispersion, dipole-dipole, hydrogenVan der Waals forces in order from weakest to strongest
67237155Dipole-DipoleVan der Waals force between neutral, polar molecules
67237156London dispersionVan der Waals force between neutral, nonpolar molecules
67237157HydrogenVan der Waals force where hydrogen is bonded to an extremely electronegative element (F, O, N)

Need Notes?

While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
