Definitly the best explaination - it only took one watch to understand it! And why? Because he explained every step using clear diagrams and didn't suddenly wizz over important bits or skip essential details. Many thanks.

This video is the best example of what it is to have a good teacher. I watched few videos of presenters on this same subject, they made it look complicated and I never saw the pattern. Watching this one clip, I did not even need to memorize, but actually saw and can repeat what he presented without taking any notes.
-
A very clear video that made a ton of sense. Now I understand how electrons are distributed in sublevels and orbitals.
-
THE best explanation for visual learners!! I had a hard time understanding orbitals until coming across your video (the textbook makes it so complex). It helps to recreate the drawings in your notes and label everything. Thank you so much!
-
You are literally the best ever, the textbooks just don't apply the break down that you do, we just need a visual realization of the concept and you provided that thank you so much!!!!! I understand!!!
-
I could never visualize the connections between shells, subshells and orbitals so this solved my misunderstandings! Thanks a mil! Question- why do electrons spin in opposite directions?
-
YOU ARE SUCH AN ANGEL! YOU BLESSED ME WITH THIS VIDEO! I HOPE GOD BLESSES YOU WITH LOTS OF HAPPINESS!❣️😭
-
By far, you were the only one that helped me understand this! I thank you so so so much. Been searching everywhere and I finally got it! keep up the amazing teaching!! Forever grateful!!!
-
I'm trying to understand this since 4 years ! very clear lecture. loved it. Now I wont forget this ever. Thanks a lot.
-
Just to clarify, electrons don't actually "spin." That aside, this is a superb presentation. Very very well done.
-
I could not explain how grateful I am, I finally understood this, and I just had to watch the video Once.
-
I really admire that you create a visualization for orbitals, sublevels, etc. because it is really difficult to comprehend in my brain something so small as electrons. I appreciate you for that!!! Definitely subscribed to your channel
-
I have really struggled to visualise and understand the connection between levels and sublevels but your drawing at 6:50 does it perfectly. Thank you v much!
-
Seriously, the best video I have come across. Thoroughly detailed, I love the use of the pictures and words they go well hand in hand. This video is the definition of how to teach a student any particular concept. Extremely Well done!
-
I found this youtube for my son, that is the best explanation I see. I hope all teachers like Richard. Thanks Richard. You are the best
-
I studies these 35 years back. When my son in AS level ask me to explain and help him, I hit upon this video. 12min is all it took to refresh. Thank you.

"The best conceptual video i have ever seen " thanx a lot i needed that part

Hello, This is by far the best video I have ever watched about electron configuration and electron orbitals. I was really struggling in class, I watched many videos and read many articles, but this video is by far the best. I loved the diagrams; they really helped me visualize and actually understand the concepts. Thank you so much! I can't thank you enough!
-
This is one of the most wonderful videos I've come across. You broke this down so simply. You have a gift. Thank you!
-
Thank you so much for teaching it perfectly! Thanks a million!
