It was discovered in 1937 by scientists Emilio Segrè and Carlo Perrier. Its name comes from the Greek word “technetos” meaning artificial, because it was the first element to be produced artificially. Technetium is a shiny, silvery-grey metal, and it’s radioactive. But don’t worry—it plays a huge role in hospitals! Doctors use it in medical scans, especially in heart imaging and bone scans, helping to diagnose conditions that might otherwise be hard to spot. While mostly synthetic, technetium can be found naturally, though in extremely small amounts. It occurs as a decay product in uranium ores and can also be detected in stars like red giants. Even though it’s rare on Earth, technetium is sprinkled across the universe! With an atomic weight of around 98, its electron configuration is [Kr] 4d⁵ 5s². It melts at 2,172 ºC and boils at 4,877 ºC. That’s your Technetium from 60-Second Science! Don't forget to like, comment, and subscribe for more educational content.
