Chapter 19
Summary:
The most rare element is astatine. This interests me because I never knew that. Quite frankly, I have never even heard of the element; I must not pay attention enough to the periodic table. Next on the rarity list is francium which is interesting because someone who speaks french is also rare due to France being on the other side of the planet. Kean then puts out a mind boggling hypothesis about how scientists not knowing to what limits the periodic table has. This book was very interesting and I would recommend it to anyone looking to read up om the history of the fascinating science that is chemistry.
