Nihonium ist ein künstlich erzeugtes chemisches Element mit dem Elementsymbol Nh und der Ordnungszahl 113. Im Periodensystem steht es in der 13. IUPAC-Gruppe und gehört damit zur Borgruppe.
Who discovered Ununtrium?
Ununtrium was first identified in 2003 by a Russian-American team who were observing the radiodecay of four atoms of element 115, known by the temporary name, ununpentium.
When was the element first discovered?
A necessary prerequisite to the construction of the periodic table was the discovery of the individual elements. Although elements such as gold, silver, tin, copper, lead and mercury have been known since antiquity, the first scientific discovery of an element occurred in 1649 when Hennig Brand discovered phosphorous.
Where is Nihonium found?
That's how we get nihonium, discovered by scientists at the RIKEN Nishina Center for Accelerator-Based Science in Japan. IUPAC says Nihon is one of two ways to say "Japan" in Japanese, and that element 113 is the first to have been discovered in an Asian country.
In what year was the superheavy element 113 observed for the first time?
Theoretically, they would occasionally fuse, forming an atom of element 113. The team achieved its first success on July 23, 2004, less than a year after starting the experiment.

Who is known as the father of chemistry?
Father of Chemistry: Most Common Answer
If you are asked to identify the Father of Chemistry for a homework assignment, your best answer probably is Antoine Lavoisier. Lavoisier wrote the book Elements of Chemistry (1787).
Which is the oldest element?
The oldest chemical element is Phosphorus and the newest element is Hassium. Please note that the elements do not show their natural relation towards each other as in the Periodic system.
How did Moscovium get its name?
The discoverers named it moscovium after the Moscow oblast where the Joint Institute for Nuclear Research is located. The name moscovium was approved by IUPAC in November 2016.
Who invented table of elements?
In 1869 Russian chemist Dimitri Mendeleev started the development of the periodic table, arranging chemical elements by atomic mass. He predicted the discovery of other elements, and left spaces open in his periodic table for them. In 1886 French physicist Antoine Bequerel first discovered radioactivity.
What is the lightest element on earth?
The lightest chemical element is Hydrogen and the heaviest is Hassium. The unity for atomic mass is gram per mol. Please note that the elements do not show their natural relation towards each other as in the Periodic system.
Is NH a metal or nonmetal?
Nihonium is a radioactive, synthetic element about which little is known. It is classified as a metal and is expected to be solid at room temperature. The element, No.
What is the newest element discovered?
Their names are Nihonium, Moscovium and Tennessine. The fourth element is named Oganesson. It was named after a Russian nuclear physicist named Yuri Oganessian.
Is Flerovium man made?
Flerovium is a superheavy artificial chemical element with the symbol Fl and atomic number 114. It is an extremely radioactive synthetic element. The element is named after the Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research in Dubna, Russia, where the element was discovered in 1998.
How is Flerovium used in everyday life?
It decays into copernicium-285 through alpha decay. Since only a few atoms of flerovium have ever been produced, it currently has no uses outside of basic scientific research.
What is element 118 named after?
Element 118 was named after Yuri Oganessian, a pioneer in the discovery of synthetic elements, with the name oganesson (Og).
Does element 115 really exist?
If you've learned all the elements from actinium to zirconium, it's time to head back to the periodic table, where there's a new, extremely heavy element in town. The new element doesn't have an official name yet, so scientists are calling it ununpentium, based on the Latin and Greek words for its atomic number, 115.
