    The steps are
    1) Count the total number of valence electrons
    2) Connect all atoms with single bonds
    3) Add in lone pairs such that all atoms that want an octet has an octet
    4) Count total number of electrons in lewis structure and compare it to the number you calculated in part 1
    5) If the number matches up, then you're done!
    6) If there are too many electrons, form double or triple bonds
    7) If there aren't enough, add lone pairs on central atoms until you have the correct number of electrons
    Examples include:
    CH2Cl2
    HCN
    BrF5
    By the end of this video, you'll know exactly how to draw lewis structures.

    So straightforward. My teacher was a little bit vague on lewis structures and now I can just memorize a few steps and be done with it.
    Thanks!

    It's so simple. It's so easy to understand and follow. My high school chem teacher made it so much harder.

    Good. It would be perfect good if you show the Periodic Table each time where you got the variance electrons for each element

    Yo, I have a question.....I understood that if we have H then its at the terminal and if C then in middle but with BRF5 we had none and you took Br in the middle so my question now is why? If we do not have C AND H, how do we decide which is gonna be in the middle?

    • @oishiray2506
      @oishiray2506 2 роки тому +3

      The least electronegative atom tends to be the one in the center. We know that Fluorine is the most electronegative atom on the PT, so Br must be the central atom. Hope that helps!

    • @isabellaseto4571
      @isabellaseto4571 2 роки тому +1

      hydrogen can form one bond so it can't be in the middle so it has to be terminal

    • @soniamammadova1891

      Also, most atoms are bonded to a single atom. Here there are 5 F and 1 Br, so F atoms bond to central Br atom.

    Why does Br have 10? You loved too fast when you were trying to explain this. But thank you!
