點解ionic bond係””””directional”””” electrostatic force

點解ionic bond係""""directional"""" electrostatic force
而covalent bond 係""""non-directional"""" electrostatic force

5係好明strong covalent bonds within molecule 同weak inter-molecular forces between molecule點解
如H2>>hydrogen
如果h同h之間既係strong covalent bond咁weak van der waal's force係邊

✔ 最佳答案

ionic bond係""""non-directional"""" electrostatic force beause ionic 係force between the oppositly charged ions,charge 係圍住ion的四周,當佢吸引oppositly charged 的ions 既時候,ions會吸住四方八面既oppositly charged ions,so it is non-directional. covalent bond is directional beause it is the electrostatic force with the shared electrons and the nucleus between the bonded atoms.佢係個force betwwen SHARED ELECTRONS and the nucleus between the bonded atoms ONLY,so it is diresctional.
