The Periodic Table is a fascinating patchwork of our elemental framework… and we are often adding to it with short-lived elements of unpronounceable names… but what's the story with technetium? How ...

Scientists spent years searching for Technetium, a chemical element that came, in time, to play a crucial role in medical diagnosis. So crucial in fact that a new search is already under way - to find ...

The story of the last element to be discovered out of the first 92 catalogued in the periodic table is told by Eric Scerri, who reminds us that technetium can be found a little closer to home than ...

When the periodic table was being put together in the late 1800s, a hole remained in the center of the middle row of transition metals where element 43 should be. This space stayed vacant until 1937, ...

For the first time, a research team from the University of Cologne has observed the electron capture decay of technetium-98, an isotope of the chemical element technetium (Tc). Electron capture decay ...

Technetium is essential for medical imaging, yet supplies of this short-lived radioactive synthetic element are far from guaranteed. Show more Technetium is essential for medical imaging, yet supplies ...

Technetium carbide does not exist -- it was pure technetium that was mistakenly considered as such, say physicists. This is important from the view point of chemistry of transition metal carbides ...
