A grade 5 Covenant College student has set the Guinness World Record for fastest time to recite periodic table from memory.

The periodic table, first invented by Dmitri Mendeleev in 1869, groups the 118 known chemical elements according to their chemical properties.

The main reason for the molecule falling apart is that a lot of the heavier elements are not stable. Oganesson, which is number 118, has a half-life of 0.7 milliseconds.

Though this particular list is, objectively, stupid—it still pays to be sympathetic. Ranking the periodic table is no easy task. Bismuth is—or at least should be—a no-brainer for the top spot out of ...

At the far end of the periodic table is a realm where nothing is quite as it should be. The elements here, starting at atomic number 104 (rutherfordium), have never been found in nature.

Carolyn Krause presents the second part of the three-part series on the Oak Ridge National Laboratory 's role in the discovery of elements in the periodic table. Many of them have been synthesized ...
