The Disappearing Spoon by Sam Kean Chapter 19 Summary/Reflection

Summary

  In the last chapter, it introduces the rarest element known on Earth, astatine. The next rarest element in francium, which can be explained through a long set of decayed elements and probabilities. After scientists were playing with heavy elements and stability, they came up with the idea of the “island of stability.” However, this theory basically rests on francium and now to stabilize the nuclei of elements. Based on this theory, scientists have been able to fill in the last rows of the periodic table with hypothesized elements all dealing with Latin and other names that scientist considered normal to them.

     Then the question to many scientists was the limits of the periodic table. The chapter then moves into how the periodic table is set up including future changes that might happen with the discovery of other matter and quantum dots. Over the years there have been hundreds of ways of organizing the periodic table but all go back to one, the original used by Bohr. Lastly, the author mentioned how we might one day make a new, re-designed, and impressive periodic table in the future that would even surprise Aliens.
