Bismuth

Bismuth is a fragile, brittle metal with a silvery-white appearance that tarnishes to a slightly pink or iridescent hue. It is chemically similar to lead but is considered safer and less toxic. Bismuth has a low melting point, making it useful in casting and metalworking. It is also used in medicine for stomach remedies, in cosmetics, and in some alloys for their unique properties. Bismuth is quite stable and non-reactive at room temperature, and it expands slightly when it solidifies, which is unusual for metals. Its distinctive color and properties make it valuable in various scientific and industrial applications.
