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?

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.
