Bismuth is a metallic chemical element with some fascinating properties. With the atomic number 83, it is 86% as dense as lead, making it curiously heavy in the hand. It is also the most diamagnetic natural substance which means it is actually slightly REPELLED by a magnet. Bismuth is one of only a few substances, water being another, that actually expands upon freezing (solidifying).
