A mineral that is a source of arsenic, typically appearing as silver-white to gray and often found in crystal form.
Arsenopyrite is often mined for its arsenic content.
Arsenopyrite is formed from "arseno-" (from Greek "arsenikon", meaning arsenic) and "pyrite" (from Greek "pyrites", meaning of fire or flint). The word refers to a mineral that contains arsenic and has a metallic luster, resembling fire in its appearance.
Think of 'arsenic' as the key element in arsenopyrite, combined with 'pyrite', which relates to fire, helping you remember that this mineral contains arsenic and has a fiery appearance.
