| Front | Name and explain differences between physical properties of ionic and simple covalent substances |
| Back | Melting point is higher for ionic - lots of energy needed to break strong ionic bonds between oppositely charged ions-SC have weak intermolecular bondsState at RTP - ioinic are solid, SC are liquidElectricity - ionic conduct when liquid/molten, charged particles free to move-SC - no charged particlesSolubility - ionic are - ions attract polar water molecules |
