chemistry..ionic bond

physical properties of ionic compounds:
  1. boleh di electrolysed bile dalam keadaan molten or aqueous..
  2. mngndungi free moving ions..
contohla..sodium ade 11 electron..klau nk bgabung dgn chlorine..ken derma kt chlorine 1 electrone sbb chlorine ade 9 je electron..

bile Na+ derma 1 electron kt Cl-...dorg akn jd sme bilangan electron..iaitu..Na=2.8..Cl=2.8 jgak..
