Selected article
Bidenium is a hypothetical element with atomic number 893. It is named after former vice president, and 45/46th and current president of the United States Joe Biden. Like all elements after lead(excluding stableisotopium), Bidenium has no stable isotopes. Its most stable isotope is ²²³¹Bid. Read more...

Did you know...

 * This wiki began circa 2013 by User:PlanetStar?
 * When we made the Obamium page, it ended up getting featured in one of the Obamium memes?
 * Mumbaia has tons of stable isotopes, even though it has such a high atomic number?
 * Elements such as Enneaneganeutronium, known as "polyrotalies", can loop past infinity and big omega, into the negatives?
