Element 99 — mysterious and exceptionally radioactive — sits inconspicuously in the bottom row of the periodic table. Named for legendary physicist Albert Einstein, einsteinium has been one of the ...

Feb. 3 (UPI) --Scientists have, for the first time, measured the bond distance of einsteinium, one of the most radioactive and difficult to make elements on the periodic table. Researchers detailed ...

Since element 99 -- einsteinium -- was discovered in 1952 from the debris of the first hydrogen bomb, scientists have performed very few experiments with it because it is so hard to create and is ...

The first-ever discovery of an extraterrestrial radioactive isotope on Earth has scientists rethinking the origins of the elements on our planet. The tiny traces of plutonium-244 were found in ocean ...

Nearly 80 years after scientists at Oak Ridge National Laboratory discovered an extremely rare radioactive element called promethium, a team at the lab published a landmark study on the subject that ...

Polly Arnold is drawn to challenging problems at the far reaches of the periodic table. “It’s all about the f block,” she says of the work in her group, which is split between the University of ...

This lesson utilizes an adaptation of the board game Periodic: A Game of the Elements to help students better understand both general periodic trends and the law of conservation of energy. This ...
