In 1766, there was a red rock discovered in a cave in Siberia. That material was referred to as red lead.
Later on, in 1798, a French scientist named Nicholas Louis Vauquelin was studying the red lead, now known as crocoite. He dissolved it in acid, precipitated the lead, filtered the rest off, and focused on the remaining.
In the remaining liquid, was me. He named me chromium, after the Greek word Chroma- which means color, because he was impressed at the range of colors I had. He also found me in emeralds and rubies.
I am a silver, lustrous and also a very hard metal. I am odorless, tasteless, and also malleable.
This one time, I was in a lab being studied, and they decided to burn me.I thought it would hurt, but instead I turned green.
I am also called a construction worker, because I work on your body, and on buildings.
