Chapter 9 - Poisoner's Corrider

Dustin Lefever


Chapter 9 was mainly about some of the poisonous elements on the periodic table. Within this chapter, five elements were discussed: cadmium, thallium, bismuth (which isn't actually poisonous), thorium, and americium. The point of using these specific elements was to show the different types of poisoning that can occur. The first two were more so the weakening of the body from the inside type of poisoning. The elements themselves acted as different (necessary) elements and destroyed the victims from the inside. Bismuth isn't poisonous, but was used as a transition due to be slightly radioactive. The transition lead to the last two elements, which cause radiation poisoning, which mainly burns your skin rather than kill you from the inside.

Where Elements are Found in Nature

Cadmium: Cadmium is a very abundant element. It can be found across the world. One place it can be found is the mines in Kamioka, Japan.

Thallium: Thallium can be found in many places. One place Thallium can be found is Xiangquan, China.

Bismuth: Peru, Japan, Mexico, Bolivia, and Canada are the biggest producers of Bismuth. Bismuth is abundant in these places.

Thorium: Thorium is more abundant than elements like gold. About 20% of the worlds supply is found in the U.S.

Americium: Americium cannot be found in nature.

Importance of Element (uses)

Cadmium: Cadmium is mainly used in rechargeable nickel-cadmium batteries.

Thallium: Thallium used to be used in rat poison and can be found in infared radiation detectors.

Bismuth: A form of Bismuth can be found in Pepto Bismol. Other forms can be found in things like fire detectors and fire extinguishers.

Thorium: Thorium can be found in electronic devices, like television.

Americium: Americium can be found in smoke detectors.

All of these are poisonous, except for bismuth which can be used in medicines.

Element Founding

Cadmium: Found during the 1800's in Hanover, Germany. It was named after a character in Greek Mythology named Cadmus.

Thallium: Found in 1861 by Sir William Crookes in London. It was named after the Greek word "Thallos" that translates to "green twig".

Bismuth: Found during the 1400's by an unknown Alchemist. Likely a different pronunciation of the German word "weissmuth" which translates to "white substance"

Thorium: Found during 1828 in Stockholm, Sweden. It was named after Thor from Scandinavian mythology.

Americium: Found during 1944 in America. Likely named after America.

Unique Appearance

Cadmium: Silver with a blue tinge.

Thallium: Silvery.

Bismuth: Silver with a pink tinge.

Thorium: Silvery.

Americium: Silvery

Overall Summary

These elements have various different uses. From a substance found in batteries to a medicine that helps your stomach. However, what brings them all together is their factor of being poisonous. From poisoning that occurs on the inside to radiation poisoning, they are brought together because of poison. Of course bismuth isn't poisonous, but it leads a transition from one type of poisoning to another. Their importance to the world isn't very specific, however, most of them have led to big incidences and are in very commonly used technologies.
