What is the most unknown element?
Discovered in 1940, astatine (element number 85) leaves a “curious void” in the periodic table of the elements: Its properties in solid or liquid, or condensed form, are simply unknown, report researchers.
What is the coolest element?
Sulfur . You usually think of sulfur as a yellow rock or powder, but one of the cool things about this element is that it changes color under different conditions. Solid sulfur is yellow, but it melts into a blood-red liquid. If you burn sulfur, the flame is blue.
What is the undiscovered element?
The last naturally occurring element to be discovered was francium (87) in 1939. Since that discovery, plutonium (94), neptunium (93) and astatine (85), which were initially created in the lab in 1940, have since been found in nature.
What’s the rarest element in the universe?
Astatine is the rarest element on Earth; only approximately 25 grams occur naturally on the planet at any given time. Its existence was predicted in the 1800s, but was finally discovered about 70 years later. Decades after its discovery, very little is known about astatine.
Is there a 120th element?
