Is element 111 radioactive?

What is the name of an element of an atomic number 111


So I was a bit sad when in 2004 a joint working party of the International Union of Pure and Applied Chemistry and International Union of Pure and Applied Physics recommended that the name of element 111 be changed to roentgenium, symbol Rg.

What is element 111 used for

Uses of Roentgenium: The only uses of roentgenium are for scientific study, to learn more about its properties, and for the production of heavier elements. Roentgenium Sources: Like most heavy, radioactive elements, roentgenium may be produced by fusing two atomic nuclei or via decay of an even heavier element.

Is element 111 a metal

Roentgenium is a chemical element with symbol Rg and atomic number 111. Classified as a transition metal, Roentgenium is a expected to be a solid at room temperature.

Has element 119 been made

Ununennium, or element 119, is a predicted chemical element. Its symbol is Uue. Ununennium and Uue are substitute names made by the IUPAC, (meaning "one-one-nine-ium" in Latin) until permanent names are made. Ununennium is the element with the smallest atomic number that has not been created yet.

Who found element 111

Discovery: Element 111 was discovered by the Gesellschaft fur Schwerionenforschung team led by Peter Armbruster and Gottfried Münzenber in late 1994. They produced three atoms of 272Rg. Roentgenium is a radioactive, synthetic element about which little is known.

Does element 116 exist

Element with atomic number 116 Livermorium (Lv) The name was chosen to honor Lawrence Livermore National Laboratory (LLNL, established in1952) located in the town of Livermore, California, United States of America.

Does element 120 exist

Unbinilium, also known as eka-radium or element 120, is the hypothetical chemical element in the periodic table with symbol Ubn and atomic number 120.

Has element 123 been discovered

In real-life science, element 123 has yet to be discovered.

Is element 119 real

Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119.

Does element 121 exist

Unbiunium, also known as eka-actinium or simply element 121, is the hypothetical chemical element with symbol Ubu and atomic number 121.

Does element 117 exist

tennessine (Ts), artificially produced transuranium element of atomic number 117.

Who discovered element 111

Roentgenium was first created in 1994 by the GSI Helmholtz Centre for Heavy Ion Research near Darmstadt, Germany. It is named after the physicist Wilhelm Röntgen (also spelled Roentgen), who discovered X-rays. Only a few roentgenium atoms have ever been synthesized, and they have no current practical application.

Does element 126 exist

Unbihexium, also known as element 126 or eka-plutonium, is the hypothetical chemical element with atomic number 126 and placeholder symbol Ubh.

Can element 137 exist

Element 137 is Untriseptium (Uts), it is a hypothetical element and its name is temporary as it hasn't actually been discovered. The current name literally means 137. Many believe if ever discovered it will be named after the physicist Robert Feynman as he predicted the periodic table would end at element 137.
