Hi folks! Here is the answer to the Friday Element Quiz: Question: I am a type 2 semiconductor and a ductile HCP metal. I am radioactive and three of my isotopes are relatively long lived with low energy beta rays and very weak gamma rays that pose only a moderate threat. Who am I? Answer: I am the element Technetium (Tc), #43 on the Periodic Table Bonus points - This element has a characteristic property that is unique/the best of all the metallic elements. What property is it? Hint - it has to do with temperature Bonus points answer: the highest ambient pressure superconducting transition temperature (11.4K) No winner this week so Doug's chair is safe. Hope to see folks at IPC next week.
