rainee SG hmm...tink need two rings...cos aluminium will have an excess of 3 electrons? then oxygen lack 3? so...they will form an ionic bond... i cant really show how to draw here...
rainee SG the rings get darker when i m stressed out la... after the stress period it will be less dark, but still can be seen...
ndmmxiaomayi SG I lazy to draw, show you the website with the diagrams. http://www.wbateman.demon.co.uk/gcse2003/gcsesums/chemsums/bonding/bonding.htm
rainee SG how many protons does oxygen have? i dun have my table with me right now, so cannot check directly...
ndmmxiaomayi SG Mind is dark throughout, stress or no stress. And can't be bothered to do anything to it. Enough sleep also no use.
rainee SG oh seow...tink u need more than 2 rings... tink the formula is Al2O3...pai seh...need 2 aluminium and 3 oxygen..
ndmmxiaomayi SG Half my trademark, but I only recognized as my small size as trademark. Panda eyes... whatever lah.
