WebBismuth was discovered by an unknown alchemist around 1400 AD. Later that century it was alloyed with lead to make cast type for printers and decorated caskets were being crafted in the metal. Bismuth was often confused with lead; it was likewise a heavy metal and melted at a relatively low temperature making it easy to work. WebJun 13, 2024 · Which of the following element does not show allotropy? (a) Nitrogen (b) Bismuth (c) Antimony (d) Arsenic Solution: (a) Nitrogen does not show allotropy due to its weak N – N single bond. Therefore, ability of nitrogen to form polymeric structure or more than one structure become less. Hence, nitrogen does not show allotropy.
