Chemistry Nihonium
Nihonium
Nihonium (Nh) is a chemical element with the atomic number 113. It is a synthetic element, first synthesized in 2004 at the RIKEN Nishina Center for Accelerator-Based Science in Japan. Nihonium is the heaviest element in the periodic table that has been synthesized in macroscopic quantities.
Synthesis
Nihonium was first synthesized in 2004 by a team of Japanese scientists led by Kosuke Morita. The team bombarded a target of bismuth-209 with a beam of zinc-70 ions. This reaction produced a single atom of nihonium-278, which decayed by alpha emission to moscovium-274.
$$^{209}Bi + ^{70}Zn \rightarrow ^{278}Nh + ^{1}n$$
$$^{278}Nh \rightarrow ^{274}Mc + \alpha$$
History
The name “nihonium” was proposed by the Japanese team that first synthesized the element. The name is derived from “Nihon”, the Japanese name for Japan. The International Union of Pure and Applied Chemistry (IUPAC) officially recognized the name “nihonium” in 2016.

Abbreviated Electron Configuration
An abbreviated electron configuration can also be used to represent the electron configuration of nihonium. This notation omits the electron configurations of the inner shells and only includes the valence electrons.
The abbreviated electron configuration of nihonium is:
$$[Rn] 5f¹⁴ 6d⁹ 7s² 7p¹$$
This notation indicates that nihonium has:
- The same electron configuration as radon (Rn) for the inner shells
- Fourteen electrons in the 5f orbitals
- Nine electrons in the 6d orbitals
- Two electrons in the 7s orbital
- One electron in the 7p orbital
Valence Electrons
The valence electrons of nihonium are the electrons in the outermost energy level, which are the 7s and 7p orbitals. Nihonium has three valence electrons, which are involved in chemical bonding and determine its chemical properties.

Nihonium Uses
Nihonium (Nh), also known as element 113, is a synthetic radioactive element that has no known practical applications due to its extremely limited production and short half-life. Here are some potential areas where nihonium could be used in the future, although these are purely speculative and subject to further research and development:

It’s important to note that these potential uses of nihonium are highly speculative and require extensive research and development before they can be realized. Nihonium is currently produced in very small quantities and has a very short half-life, making it challenging to study and utilize its properties.
Nihonium Effects
Nihonium (Nh), also known as element 113, is a synthetic element that was first synthesized in 2004 at the RIKEN Nishina Center for Accelerator-Based Science in Japan. It is an extremely rare and radioactive element with a very short half-life, making it difficult to study. However, scientists have been able to observe some of the effects of nihonium on other elements and materials.
Effects on Chemical Reactions
Nihonium has been found to have a significant effect on the rate of chemical reactions. When added to a reaction mixture, nihonium can cause the reaction to proceed much faster or much slower than it would normally. This effect is thought to be due to nihonium’s ability to change the electronic structure of the other elements in the reaction mixture.
Effects on Materials
Nihonium has also been found to have a significant effect on the properties of materials. When added to a material, nihonium can make it stronger, harder, or more resistant to heat and corrosion. This effect is thought to be due to nihonium’s ability to change the crystal structure of the material.
