Use END 3.3 ionic 3.3-1.7 mostly ionic 1.7-0.5 polar covalent 0.5-0 slightly polar covalent 0 nonpolar covalent
Intermolecular forces
Dispersion- momentary dipoles between all molecules through positive nucleus and e-
Dipole to dipole- polar molecules only, between the slightly - and + end
Hydrogen bonds- super strong dipole to dipole forces with FON
(Extra large negative end)
Covalent properties polar Particles Force/bond Boiling point Electrical Hardness Soluble Electronegativities Ex
Polar molecules Dipoles Low intermediate Low Soft Soluble in polar Moderate ENDS Ice
Nonpolar covalent properties Particles Force/bond Boiling point Electrical Hardness Soluble Electronegativities Ex
Atoms or nonpolar Dispersions Lowest Extremely low Very soft Soluble in nonpolar Similar Frozen oxygen long hydrocarbon chains
Ionic properties Particles Force/bond Boiling point Electrical Hardness Soluble Electronegativities Ex
Positive and negative ions Attraction between ions High Only when melted Hard and brittle Polar solvents Widely different electro Table salt
Metallic properties Particles Force/bond Boiling point Electrical Hardness Soluble Electronegativities Ex
Sea of e- delocalized Metallic bond is string Intermediate to high Good Soft to hard, malleable and ductile Molten metals Low electro Copper penny
Network covalent properties Particles Force/bond Boiling point Electrical Hardness Soluble Electronegativities Ex
Atoms Covalent bonds strong Highest Doesn't conduct Hardest things known Insoluble Bond in four directions Diamond
Order of boiling points lowest to highest
