  • If you lose two electrons,the charge will be 2+, not 2-

  • Please give me the exact point in the video where I make this mistake so I can edit it. Thank you!

  • You're officially my unofficial chem teacher this semester. Why can't my professor, head of the chem department, teach like this? She's terrible.

  • thank you for the videos really a big help..I was a frustrated chemistry student..due to my chem teacher,he's terrible,talking the board all through out the period.

  • please continue to make videos, you're fantastic.

  • You're an excellent teacher. I wish you teached at my school.

  • You make chemistry understanable and fun. I feel like I am in a theatre and a movie is about to start when you begin to speak. Cool.

  • @deaneden79 We problably attended the same school!

    LOL

  • i take IB chem and this is what gets me through the class...these videos are so helpful :D

  • make sure this is correct starting at 1:53

  • @MarkRosengarten

    I was referring to 2:16 when you said "you loose one electron it's negative one..." Loosing one electron would increase the charge of the atom,would it not? I could be wrong.

  • He is revering to the spot around 2:08, when you are talking about reduction, something he apparently doesn't understand.
