Chemistry Help! Drawing Lewis electron dot structures for water (H2O) and ammonia (NH3).




Instead of using math to account for the valence electrons, I draw all of them on the paper, and "connect the dots!" This way, I don't make silly math mistakes. For more complicated structures, it helps me understand formal charges.

  • How to know if a molecule has bent structure (dipol)?

  • Measure the dielectric constant or make a prediction using the VSEPR theory.

    See "Chemistry: Electronic and Molecular Geometry" video for help with this.

  • u teach it better than the guys love u

  • @fatboyj182 No shit, fat boy

  • Sorry for the long dang comment! I write alot, I have lots to say.. I need to shut up now. thank you! =D

  • You are helping me so much more than my real teacher! I am in a Chemistry Honors class. And believe me I have never been so confused in my life! Thank you so soo sooo much!!! Please keep doing what you are doing, because you are saving so many people's lives. And I agree with the person before me, thank you for showing how to put the dots in place.. that was what was messing me big time. I got the rest, except for that thankkk youuu agaaainn! God bless youuu! =D

  • Thank you for actually showing how to get the freaking dots in place. My teacher assumed that we knew how to do it and never showed us. -_-
