The Episodic Table of Elements is a science-history podcast exploring the culture and chemistry behind every element on the periodic table.

We’re traveling in order of increasing atomic number: Episode 1 is hydrogen, episode 2 is helium, and so on.

Each episode stands on its own, but the show does provide a basic chemistry education that builds on itself over time. If you’re new to the show, start with Episode 0: Everything The Light Touches. It’s a very short episode that outlines the show’s format, and introduces you to the scientist who first saw a vision of the periodic table in a dream.

You could also visit the episode archive and start anywhere on the periodic table you like!

Episodes are released when I’m satisfied with them. Sometimes there are long gaps between episodes, but in time, I will complete the entire table.

Content is generally appropriate for all audiences; however, sometimes the discussion touches on topics like war and suicide. I include these stories because I believe they’re historically significant, but I also provide a content warning if an episode ventures into darker territory than usual.

Comprehensive show notes provide additional context for anyone who’s curious — there’s always something left on the cutting room floor. I’m not able to spend as long on these as the rest of the episode, so if you have any questions, comment on the post.

Each post also provides a full transcript with comprehensive citations, not just so people can check my facts, but also to provide a jumping-off point for anyone who would like to do further research. However, please note that I rarely adhere to any official format for these citations.

The Episodic Table of Elements is written, hosted, and produced by T. R. Appleton, with music by Kai Engel and occasional contributions from Josh Crowley.
