KM was having a very difficult time understanding the concepts of valence electrons and therefore covalent bonds, so I have spent a lot of time sending her links, videos, and explanations to try to make it clearer. Last night I sent her this ONE and she finally got it. "You should have shown me this one to begin with. I need pictures, Mom, I NEED PICTURES!!!"
The question that I then presented to her was "Did you understand it simply because of this picture? OR Did you understand the picture because of all the reading and videos that you watched on the subject?" She was a bit shocked and moved on without answering me, but really how will we ever know?
