1.An element's name must be approved by the International Union of Pure and Applied Chemistry, or I.U.P.A.C., in Geneva, Switzerland.
2.The heaviest element gas is radon at room temperature. (There may be heavier ones, but they are compunds not atoms). It was discovered by Friedrich Ernst Dorn in Germany in 1900, but he first called it niton, until 1923.
3.The lightest gas is hydrogen, it is also the lightest of all elements.
4.The element with the highest melting/freezing point is carbon at 6,381 degrees Fahrenheit (3,527 degrees Celsius).
5.The element with the highest boiling point is rhenium at 10,105 degrees Fahrenheit (5,596 degrees Celsius).
6.The element with the lowest melting/freezing point is helium at -458 degrees Fahrenheit (-272.2 degrees Celsius).
7.The element with the lowest boiling point is also helium at -452.07 degrees Fahrenheit (-268.93 degrees Celsius.
8.The word "atom" comes from the Greek word atomos, meaning "uncut."
9.In 1964, scientists in Russia discovered element 104, and suggested the name Kurchatovium and symbol Ku in honor of Igor Vasilevich Kurchatov. Then in 1969, scientists in the U.S. also found element 104, and propsed the name Rutherfordium (symbol Rf), in the honor of the New Zealand physicist Ernest R. Rutherford. To get the names past the I.U.P.A.C., it won with rutherfordium.
10.The first and relatively pure atom of tantalum was produced by von Bolton in 1907.
