ASMR Drawing Lewis Dot Structures: four examples

What better way could there be to freshen up on your Lewis Dot structure prowess than to experience a pointed pen and black ink ASMR tutorial? I go through examples of a "regular" molecule (NH3), an anion (BF4-), creating multiple bonds in CO2, and an expanded octet (SF4). Let me know other chemistry topics would you like me to draw or explain! Thank you for subscribing.
