  1. ??? Glided, they donot have the same amount of lone pairs!!! Oxygen has 6 electrons in the outer shell, and it needs another 2 electrons to form full outer shell. It share 2 electrons with 2 hydrogens, while those 2 hydrogen obtain full outer shell as well, so, 6-2= 4 4 electrons are not in valence between two obitals of different atoms, so.. there are 2 lone pairs.. For NH3, there is one lone pair... Any change on this? Albert
  2. Again, for the 4th quote in my previous message, I dont really get the meaning for that,.. because why use "only" for NH3, while both NH3 and H2O have the same amount of lone pairs?
  3. Any way, I think I should stop here... because things are getting out of control for me to understand!!
  4. PrimaryGun, are u Chinese???? because I find ur logic of conversation in English a bit different to others here.... ANy way, I dont really get the meaning for this,.. and I think you made a mistake on either NH3, or H2O, because why use "only" for NH3, while both have the same amount of lone pairs? Thx in advance!! Albert
  5. Well, any other can answer my question of my previous post????
  6. Any body can help on my previous message???
  7. OK..... any way, again... according to the table Glided provided, which one has a stronger electronegativity, NH3 vs H2O??
  8. Glided, You mean H2O instead of OH, right? because OH is not a molecule, it's an ion... Secondly, according to the table, which one has a stronger electronegativity, NH3 vs H2O?? thx, Glided Apreciate for furthur responds
  9. ................... but any way, you speak just as young as any body else here.... Cool, I wish my grandparents can speak to me like this
  10. What situation H3O+ is formed? secondly, again, is there any compound having this ion?
  11. Ophiolite, thx.. By the way, back to forty years ago????? do you mean "forteen years ago"?
  12. The only thing I dont get is: How do you know which molecule is polar and what is its negativity? By the way, PrimaryGun, you said that the more difference on negativity of two atoms, the more chance of ionic bonding it becomes.... but, is the range of negativity between hydrogen and oxygen very small? how can you know that? Albert
  13. thx thx thx !!
  14. by combining what????
  15. umm... but that's between two water molecules!!
  16. Well, I think so.., as an example from one of my thread, NH3, an amonia molecule, has 3 hydrogen pulling the Nitrogen atom, which Nitrogen is the lone pair... and if it is near a hydrogen ion, it shall be attracted to it... hence forming a NH4 ion... but on the other hand, how come the lone pair of water cant make an ion out of this way?
  17. So if Hydrogen can loose electron, this confuses me.... because, why H2O does not form in ionic, instead covalent, since it will be more stable? as oxygen atom need to take up 2 more electrons, as 2 hydrogen atoms can provide so... Albert
  18. How many shells does a hydrogen atom have? I thought it only has 1 shell, because according to the periodic table, the row number indicates the number of shell (orbit) as Hydrogen is placed in the first row. Secondly, if it has only 1 shell, does that mean hydrogen can never loose 1 electron in its only shell? because otherwise it obtains no electron at all in its shell during ionic bonding. Any help?
  19. Would any molecule with partial charge ever bonded with any ion with a complete charge?
  20. For 5gb/day, how come the web hosting solution company can provide the bandwidth much cheaper than if we get it at home?

    For curiosity, what does that image look like?
  22. Any body can help me....?

    so............. Does that imply the more symetrical has a less alien-like face? I was thinking that our brain can be used as acurate detector on the symetrical shapes of human body, because I was using mathematics to measure what parts of the face of my ugliest female mate that are'nt symetrical, and fail to do so, but still, looks ugly to me
