Russian chemist Dmitri #Mendeleev was the first to arrange elements in the structure we know as the periodic table. Mendeleev was a lover of card games and used a solitaire sorting strategy of columns and rows to help arrange the elements.

NASA Scientific Visualization Studio | Periodic Table of the Elements: Origins of the Elements

The periodic table organizes all the known elements by atomic number, which is the number of protons in each atom of the element. This version of the table, which draws on data compiled by astronomer Jennifer Johnson from Ohio State University, shows our current understanding of how each element found on Earth was originally produced. Most of them ultimately have cosmic origins. Some elements were created with the birth of the universe, while others were made during the lives or deaths of stars. The Nancy Grace Roman Space Telescope will help us understand the cosmic era when stars first began forming. The mission will help scientists learn more about how elements were created and distributed throughout galaxies.The related Tumblr post is here. ||

From the iron in your blood to the calcium in your bones, the stuff that makes 'you' was forged in stars. It's even in your DNA – carbon, oxygen, nitrogen, etc. all came from ancient stars to become planets, puppies and you. Happy #PeriodicTableDay! https://go.nasa.gov/40AAgxJ

Since it’s #PeriodicTableDay a reminder that when the official discovery of element 117 was announced I, for laughs, proposed it be named octarine (Oc) in honour of Sir Terry Pratchett (who had died a few months before).

The petition went viral and got over 51k signatures.

Sadly, IUPAC weren’t having it and 117 was eventually named tennessine (Ts), after Tennessee where the Oak Ridge National Laboratory is based.

Which. Fine.

It clearly wasn’t *precisely* a million-to-one chance.
