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 ...

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 ...

Word origin: The word technetium comes from the Greek technetos, artificial. Discovery: Technetium was the first element to be produced artificially. Element 43 was predicted on the basis of a gap in ...

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, ...

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 ...

Technetium is essential for medical imaging, yet supplies of this short-lived manmade element are far from guaranteed. We see a technetium scan in progress and a cow being milked, and hear the yarn of ...

ONE of the first inklings that chemistry has an underlying pattern was the discovery, early in the 19th century, of lithium, sodium and potassium—known collectively as the alkali metals. Though ...
