Which metal is known for its high brittleness and pinkish hue?

• A. Copper
• B. Silver
• C. Bismuth
• D. Lead

Answer: (C)

Bismuth is known for its high brittleness and distinctive pinkish hue, which sets it apart from other metals. This characteristic coloration is due to the oxidation of its surface, which can give it an iridescent appearance and varies depending on its oxidation state. The brittleness of bismuth means that it breaks or fractures rather than deforming, which is a significant property to consider in applications. In contrast, copper has a characteristic reddish-brown color and is known for its malleability and ductility rather than brittleness. Silver is a highly malleable and ductile metal recognized for its shiny luster and bright appearance but does not exhibit the pink hue associated with bismuth. Lead, while also relatively brittle compared to other metals, has a bluish-gray color rather than a pinkish one. Thus, the unique properties of bismuth, both in color and structural characteristics, make it the correct answer.
