Show HN: The Molecular Geometry ABC's (pdf book)

My daughter and her friends created this book, including the illustrations in it. I thought it was pretty cool way to learn molecular geometry, so sharing it with the world.

They are tenth grade high school students, and would be stoked to read the comments.

[NOTE: While I am aware Show HN requires showing your work, my daughter and her friends do not have HN accounts. Hence I am posting on their behalf. I have obtained permission to post this. Thank you.]
