Hi! My name is Arsenic and I am the third element in the Nitrogen Group. I have two solid medications: yellow, and grey or metallic. I am a steel grey, crystalline, semimetallic (metalloid), very brittle solid. I tarnish in air, and when heated rapidly oxidize to arsenous oxide which has a garlic odour. My compounds and I can also be a very poisonous elements. I can be used as herbicides, various alloys, insecticides and pesticides. My name comes from a Persion work Zarnik (ÒÑäíÎ) meaing “yellow orpiment.” The Greek borrowed Zarnik and renamed it arsenikon.  I have been used in Persia and many other places for a long time. I was frequently used for murder back then.         My friend Phosphorus and I are very similar; I substitute in for him many times because of all our similarities This sometimes causes Phosphorus to be poisonous too. I have been classified as toxic and dangerous to the environment in many places.
