[@shurenbt]

i am so so thankful for this. you are a great man honestly. feel much better about my upcoming final

[@inasabdelgayoum9458]

I can't thank you enough.

[@veronica.theswamphag]

This just saved my life, I'm doing chemistry independently so these videos are incredibly helpful

[@allenmoyashides8395]

This is such a great video, but I kept on facing problems with 2s as at first I didn't know/understand that 'n' is a shell and each shell has it's own system thus there is not only 1s but 2s, 3s... but there is only one s in one shell and three p in one shell and so on. So for others who are reading this comment, I hope this helps.
But none the less these are a very helpful bunch of videos!!!!

[@joshuatahav2284]

khan videos have really been helpful, especially for one who has a poor chemistry background. Thanks for the good work

[@yanakochetova378]

Amazing video!! Helped me understand this topic sooooooo much more. Thank you!

[@mariamfarooq6793]

we have a self taught unit in chem right now, and this was so helpful! thank you so much
