With a melting point of 3915° F (or 2430 K), unless you work with materials that hot to begin with, chances are you’ve never run across element 43.
Initially observed to be missing from his Periodic Table, Dmitri Mendeleev predicted in 1871 the future discovery of element 43, located between molybdenum and ruthenium. Numerous scientists and experiments later, the discovery of technetium occurred in 1937, thanks to Italians Carlo Perrier and Emilio Segre.
Because of its instability to nuclear decay, technetium does not commonly occur in nature–other than in trace elements in the Earth’s crust–and the Italians can be credited for founding and naming the world’s first man-made element.
What do elements have to do with social media?
Watch the following video:
When was the last time you watched a video about the Periodic Table? It seems there’s a running series uploaded to YouTube and victim to comments about every element. If that’s not indicative of social media, tell me what is.

Several months ago,@eyecube wrote a fabulous post about the Periodic Table of the Social Media Elements, http://www.rickliebling.com/2009/02/23/the-periodic-table-of-the-social-media-elements/ as social media is really a lot like chemistry. Interesting to see the chemists using social media to tell their story.

Martyn Poliakoff…the Prof with the most scientific hair ever, after Einstein, is a good friend of mine. I interviewed him for New Scientist back in the mid-1990s on the subject of supercritical fluids, which are truly amazing substances (yes, even more amazing than his hair). The chemists at Nottingham U have definitely got social media and online video, they’re going down a storm everywhere the Periodic Videos feature
