Short Answer
1. Lewis and Clark took mercury pills, a popular medication for constipation at the time of their travels. Archeologists can track where Lewis and Clark camped by detecting mercury in the soil where the travelers dug a hole for a latrine. (Part 1, Introduction)
2. These atoms are lanthanides or rare earths. They are unique because they bury new electrons more deeply than transition metals and can hardly be distinguished from one another. (Part 1, Chapter 1)
3. Sam Kean believes it is unlikely that life is silicon-based, because when silicon combines with oxygen, the result is a solid that does not dissolve in water, and water is the chief solvent of life. Silicon, unlike carbon, is also unable to form the elaborate chemicals of living things. (Part 1, Chapter 2)
4. Mendeleev helped develop the periodic table, but he was also the first to discover that atoms are defined by their atomic weight. His discovery prompted him to leave blank spaces because he believed more elements would be discovered.
