Arsenic: For my tile, I discovered that arsenic can be used as a deadly poison, commonly found in rodent poisons. I used a skull in my tile to represent arsenic’s poisonous qualities, and added the atomic number (33), the symbol (As), and atomic mass (74.922). I was surprised to learn recently of some bacteria use arsenic in their internal structure.
