The only difference is an ionic radii is describing a charges species, Atomic radii is describing a neutral one. - Cl (-) vs Cl
Its the atomic number minus # of shielding electrons: (Z-S) - note: z-effective # corresponds with valence #
As Z-eff increases, the atomic radii decreases. trend: z-eff increases right across table.
Its a compound containing a mixture of ionic and covalent bonds Ex: graphite or diamond.
Ionic, or anything with an ionic nature
Depends: -similar sized molecules= dipole wins - size (london forces) trumps dipole force as you get larger in size.
No because ionic bonds do not form molecules so they cannot have intermolecular forces. covalent bonds are the only types of bonds that form molecules.
Ion dipole: Na+---H2O has a greater charge difference than H2O --- H2O.
- paramagnetic can be affected by a magnetic field. Diamagnetic cannot. - any atom with an odd number or unpaired valence electron is considered paramagnetic.
