It is 2018 but with the amount of bracelets you are watching I could already tell it was 2014 without looking at the date.

How do you know there are 5 valence in Phosphorus ? I see a 15 on top. I am looking at the periodic table. I am confused. Please help !

lucia nguyen remove the one from 15. There are two ways to number the periodic table columns- start from left with 1 and skip the middle transitional metals and continue with 3,4,5,6,7,8 ( all way to noble gases, so P gets 5)

Your videos are so helpful! I'm doing an online chemistry course and watching your videos has really helped me to understand some of the more difficult concepts. Could you please do a video on how to draw orbital overlap diagrams? I'm having trouble trying to teach myself how to draw them.
