Episodes

46. Palladium: The Old Razzle Dazzle 23.09.2019

Those people who've been involved with palladium's history seem to harbor a dubious predilection for stretching the truth.

45. Rhodium: The Most Precious Metal 09.09.2019

For some people, rhodium's most important aspect is its high price. For others, it's absolutely priceless.

44. Ruthenium: The Glow Cloud 26.08.2019

Element 44 is technically not named for Russia... but perhaps it should be.

43. Technetium: Naturally Synthetic 12.08.2019

It's only after we gave up searching for this element that we found it out in the universe.

42. Molybdenum: Conventional Weapons 29.07.2019

Before we talk about one big gun, let's discuss 1,500 years of military technology.

41. Niobium: No More Tears 15.07.2019

We delve into elemental etymology today, and get to investigate a chemical phenomenon.

40. Zirconium: Burning Up, Melting Down 01.07.2019

Today, we reach the last element on the periodic table -- but only alphabetically speaking.

39. Yttrium: It’s A Quiet Village 17.06.2019

Welcome to the sleepy Swedish town of Ytterby. I hope you like it, because we'll be spending an awful lot of time there later in the series.

38. Strontium: Little Town 03.06.2019

Let's look past the bad reputation this element has to learn how it's an essential part of an idyllic childhood.

37. Rubidium: What’s Cooler Than Being Cool? 20.05.2019

Rubidium is more explosive than the alkali metals above it on the table, but it's much more interesting when it's standing almost perfectly still.

36. Krypton: It’s A Metric 06.05.2019

Like argon, today's noble gas coincidentally features prominently in science fiction -- albeit in name only. But krypton also takes a place in the science factual story of international weights and measures.

35. Bromine: Come At Me 22.04.2019

Don't get too excited, because bromine is an element that brings the hammer down on both extreme emotions and extreme actions.

34. Selenium: A Fit Of Heat And Light 25.03.2019

Throughout history, copying information has been arduous, messy, and even dangerous -- until one bored, depressed man figured out the secrets of selenium.

33. Arsenic: It’s Not Easy Being Green 11.03.2019

Considering how synonymous this episode's element is with "poison," it's shocking how eager people have historically been to ingest the stuff.

32. Germanium: Harder, Better, Faster, Stronger 25.02.2019

Silicon gets all the press, but germanium was the real trailblazer of the Information Age.

31. Gallium: The Wet Bandits 11.02.2019

Meet one of the periodic table's lesser-known liquid metals -- and beware some dangerous competition from a few felonious element collectors.

30. Zinc: The Lecture Circuit 28.01.2019

Learn about some of Italy's most renowned chemists and how they inspired a most gruesome quest to conquer death.

29. Copper: Wires Crossed 14.01.2019

We get lost in the woods with a couple of little guys in today's episode, and learn about a lesser-known American Civil War.

28. Nickel: Face Value 31.12.2018

From religion to money to politics, nickel finds itself at the center of all kinds of awkward conversations.

27. Cobalt: Mischief Managed 17.12.2018

Cobalt is a tricksy little element, which means the scientists who've dealt with it the most are some of the cleverest people to have ever walked the Earth.

26. Iron: As Above, So Below 03.12.2018

Is iron a metal that's more valuable than gold, or are we forever trapped in its "hated shadow?"

25. Manganese: Undercover Operations 19.11.2018

From giant prehistoric sharks to clandestine Cold War projects, manganese is an element that has concealed a lot of secrets.

24. Chromium: I’ll Be Your Mirror 05.11.2018

It might be tempting to speed right on by, but it's worth stopping for a moment to gaze at element 24.

23. Vanadium: Beauty In The Background 22.10.2018

From freeways to firefights to unfathomable depths, vanadium can often be found quietly doing the hardest work.

22. Titanium: Dignity Over Dentures 08.10.2018

Titanium is an element valued as much for its beauty as its strength -- provided you can find a genuine sample of the stuff.
