640574883 | F2 | nonpolar and nonpolar covelant | |
640574884 | trend in Period 3 with increasing atomic number | increasing electronegativity | |
640574885 | Na2O | ionic - high melting point | |
640574886 | more polar | farther away from each other on periodic table | |
640574887 | longer carbon chain | higher boiling point | |
640574888 | polar molecule soluble in... | polar solvent | |
640574889 | Group 2 elements lose electrons and... | radius decreases because greater proton forces pull them in | |
640574890 | Water can form more h-bonds compared to... | ammonia | |
640574891 | lone pairs of electrons | always polar | |
640574892 | no lone pairs and atoms on outside are the same | non polar | |
640574893 | no lone pairs and atoms on inside are different | polar | |
640574894 | 3 atom polar molecule | bent | |
640574895 | 4 atom polar molecule | pyramidal | |
640574896 | 3 atoms without lone pairs | linear | |
640574897 | 4 atoms without lone pairs | trigonal planar | |
640574898 | 5 atoms without lone pairs | tetrahedral | |
640574899 | more than .5 electronegativity | polar | |
640574900 | less than .5 electronegativity | non polar | |
640574901 | LDF | attraction between molecules with no dipole moment or between noble gases VERY WEAK STRENGTH ex, CO2 | |
640574902 | dipole-dipole | attraction between one dipole molecule and another dipole molecule WEAK STRENGTH ex. SO2 | |
640574903 | dipole moment | when one side of the molecule has a partial positive charge and the other side of the molecule has a partial negative charge | |
640574904 | ion-dipole | attraction that exists between an ion and a dipole molecule WEAK STRENGTH ex. NaCl in water | |
640574905 | hydrogen bonds | attraction between (highly polar) molecules of F,O,N and hydrogen MODERATE STRENGTH ex. H2O | |
640574906 | surface tension | attraction of molecules to each other, creating a "film" the can support different things | |
640574907 | water polarity | will dissolve polar or ionic substances | |
640574908 | de-ionized | will not conduct electricity | |
640574909 | vapor pressure | liquid placed in closed container and the rate of condensation and evaporation are at an equilibrium | |
640574910 | volatile | liquids with high vapor pressures (evaporate easily) | |
640574911 | strong intermolecular force | low vapor pressure | |
640574912 | low intermolecular force | high vapor pressure | |
640574913 | boiling | when bubbles form in the interior of the liquid, bubble form equal to atmospheric pressure, boiling occurs when VAPOR PRESSURE is equal to ATMOSPHERIC PRESSURE | |
640574914 | lower atmospheric pressure | lower boiling point and vice versa |
