What is the 101 element?
mendelevium
At atomic number 101, mendelevium was a different type of element: the first of the trans-fermium elements.
What is the most useless element?
Thulium
Within the standard 92 elements found in nature, most have at least some practical use, the most useless probably being Thulium, which is usually the butt of jokes on the subject, but still has some actual applications (http://en.wikipedia.org/wiki/Thulium#Applications).
What does thulium symbolize?

Who invented element 101?
Harvey, Gregory R. Choppin, and Seaborg—devised a plan to produce a new element, element 101. First, the atoms of einsteinium were spread onto a thin gold foil. Since einsteinium has a half-life of about three weeks, the scientists only had about a week after receiving the element to perform their experiments.
Who discovered element 101?
Glenn T. SeaborgMendelevium / Discoverer
What is the coolest periodic element?
Plutonium. Pretty much all of the radioactive elements are cool. Plutonium is particularly awesome because it truly does glow in the dark. Plutonium’s glow isn’t due to its radioactivity, though.
What element has no uses?
Nobelium has no uses outside research. Nobelium has no known biological role. It is toxic due to its radioactivity.
Are there any elements with no use?
A few elements have no current uses, such as protactinium and berkelium. The short-lived, man-made elements starting with einsteinium have no uses at the moment either, as they don’t stick around long enough for scientists to experiment on them.
Is thulium toxic?
It is non-toxic. Thulium is found principally in the mineral monazite, which contains about 20 parts per million. It is extracted by ion exchange and solvent extraction. The metal is obtained by reducing the anhydrous fluoride with calcium, or reducing the oxide with lanthanum.
