Three New Elements of the Periodic Table

Periodic table of elements is now greater after the General Assembly of International Union of Pure and Applied Physics (IUPAP) approved the names of three new elements at the weekend. Atomic numbered elements 110, 111, and 112 were given the name Darmstadtium (Ds), Roentgenium (Rg), and Copernicium (Cn).

This element is so large and unstable so that they can only be made in the laboratory, and crushed into one another very quickly. Not much is known about this new element because they are not stable enough to be tested by experiment. They are also not found in nature.

General Assembly endorsed the proposal put forward by the name of the Joint Working Party on the Discovery of Elements, which is a joint institute of the International Union of Pure and Applied Physics (IUPAP) and the International Union of Pure and Applied Chemistry (IUPAC).

1. Darmstadtium, the element with atomic number 110, was first synthesized on November 9, 1994 at the GSI facility near the city of Darmstadt. The name of the city that is the basis of naming elements created by crashing the heavy isotopes of lead with nickel-62, which produced four atoms darmstadtium.
2. The element with atomic number 111 was officially named Roentgenium. Elements found in 1994 is getting its name from the name of the German physicist, Wilhelm Conrad Roentgen (1845-1923), the first person to produce and detect X-rays, and the winner of the Nobel Prize for physics.
3. Copernicium, the element with atomic number 112, taken from the name of the Polish astronomer, Nicolaus Copernicus (1473-1543). Copernicus was the first to declare that the earth revolved around the sun. "To honor a great scientist, who changed our view of the world," said Sigurd Hofmann, head of the team of inventors at the GSI Helmholtz Center for Heavy Ion Research in Germany. *** [LIVESCIENCE | KORAN TEMPO 3701]
