I spent a year in Chemistry classes and failed. Now after using your videos and studying privately I managed to retake the exam and get an A. Thank you very much Sal, you give me hope.

thanks for the video

This is a perfect example of why some courses should be taught online, and NOT in some boring classroom where everyone falls asleep because they don't understand. Bravo.

you said in the last video that electrons emit light when they go from a higher energy state to a lower one and they absorb light when they go the opposite way , so that would mean that in a chemical reaction where some substance steals e- from another one eg. 5s2 is stolen when 4d2 exists , dose 4d2 take the place of the stolen 5s2 and the reaction emits light? . this is probably a dumb rationalization :( , but i am dumb enough to ask it :))
