covalent bond

covalent bond ni terhasil apabila non metal atom combines with non metal atom too..
(group 14.15.16 n 17) which have a valence electron of 4,5,6 and 7

cara tuk knalpasti n nk wt ikatan covalent bond ni adlah:
  1. electron arrangement of atom X is 2.4 and the elctron arrangement of atom Y is 2.8.7.
  2. each aton X contributes 4 electrons for sharing to achieve the stable electron arrangement.
  3. each atom Y contributes one elctron for sharing to achieve the stable electron arrangement.
  4. 4 electron Y akan kongsi 1 electron dgn 1 atom X untuk menghasilkn COVALENT BOND!!!
diharapkn dpt bntu sket sbyk...gudluck tuk chem!!! chem is easy!!=_="
