This is just about the most beautiful toxic and carcinogenic metal you're likely to see. My other arsenic samples are all fairly badly oxidized, but this one is bright and shiny, and should stay that way since it's ampouled under argon. This sample was donated by Dave Roberts of DePauw University, who I got to know while I was installing the beautiful periodic table display that now graces their Julian Science Center. Dave found a bunch of surplus elements in their chemical storeroom, and naturally Max Whitby and I graciously offered to take them off his hands.
I chose this sample to represent its element in my Photographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.
