Description
Bismuth is the fifth element in the nitrogen group, and its properties are the most metal-likeof the five. Elemental bismuth is a heavy, brittle, hard metal that can be polished to a brightgray-white coat with a pinkish hue. It is not found in this state very often because it is more likelyto be combined with other metals and minerals, such as tin, lead, iron and cadmium. These aremixtures with low melting points, making them useful in fire-detection devices.
