Question : In July 2018, an experiment aboard the International Space Station cooled a cloud of atoms of which chemical element to one ten-millionth of one Kelvin above absolute zero, forming a Bose-Einstein Condensate in space.
Option 1: Rubidium
Option 2: Plutonium
Option 3: Radium
Option 4: Thorium
Correct Answer: Rubidium
Solution : The correct option is Rubidium.
In July 2018, scientists aboard the orbiting lab used the Cold Atom Laboratory to chill a cloud of rubidium atoms to a temperature just one-tenth of a degree above absolute zero, achieving the fifth state of matter known as a Bose-Einstein condensate (BEC) in space for the first time.
