History
Nihonium was first synthesized in 2003 by a team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. The team bombarded americium-243 with calcium-48 ions to produce four atoms of nihonium-278. In 2004, a team of Japanese scientists at the Riken Nishina Center for Accelerator-Based Science in Wakō, Japan, also synthesized the element by bombarding bismuth-209 with zinc-70 ions. However, the results of both teams were not fully confirmed at that time.
Further experiments and independent confirmations by research groups in the United States, Germany, Sweden, and China were conducted to validate the creation of nihonium. In June 2006, the JINR-LLNL collaboration claimed to have synthesized a new isotope of element 113 directly by bombarding a neptunium-237 target with accelerated calcium-48 nuclei. In 2012, the same team reported further experiments that confirmed the synthesis of nihonium through the reaction of calcium-48 ions with an americium-243 target.
In 2015, the International Union of Pure and Applied Chemistry (IUPAC) and International Union of Pure and Applied Physics (IUPAP) Joint Working Party recognized the element and credited the discovery and naming rights to the Riken team. The Riken team proposed the name nihonium in 2016, which was accepted by IUPAC in the same year. The name is derived from the Japanese name for Japan (日本, nihon). The discovery of nihonium is considered a significant milestone in nuclear physics, providing further insights into the properties and behavior of heavy elements.
Occurrence and production
Nihonium is a synthetic element that is not found naturally on Earth. Therefore, it has no occurrence in the Earth’s crust or atmosphere.
Nihonium is a highly unstable element with a very short half-life, which makes it extremely difficult to produce and study. It has been synthesized in the laboratory using nuclear reactions involving heavy ions. The most common method of producing nihonium is through the fusion of two lighter nuclei, typically a heavy metal target and a lighter projectile. This method requires the use of a particle accelerator and is extremely challenging due to the instability and short half-life of nihonium.
The first successful synthesis of nihonium was reported in 2003 by a team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, and in 2004 by a team of Japanese scientists at Riken in Wakō, Japan. Since then, nihonium has been synthesized in various laboratories around the world.

Interesting facts
Nihonium was named after the Japanese word “Nihon,” which means Japan, as it was discovered by a team of Japanese scientists at the Riken laboratory in Japan.
The discovery of Nihonium was announced in 2003, but it wasn’t officially recognized until 2016 by the International Union of Pure and Applied Chemistry (IUPAC).
Nihonium is an artificially produced element and has a very short half-life, which means it is highly unstable and quickly decays into other elements.
The atomic number of Nihonium is 113, making it one of the heaviest elements on the periodic table.
The discovery of Nihonium was a collaborative effort between teams of scientists from Japan, Russia, and the United States, with the Japanese team synthesizing and observing the element, and the Russian team confirming its discovery.
Nihonium is classified as an unknown chemical property and is expected to have similar properties to other group 13 elements like boron, aluminum, and gallium.
Due to its short half-life and radioactive nature, there are currently no known practical applications of Nihonium. However, its discovery helps to further our understanding of the properties of heavy elements and the nature of nuclear reactions.
