Nihonium Properties and Characteristics
Nihonium, with the atomic symbol Nh and atomic number 113, is a synthetic element that was first synthesized in 2003 in a joint collaboration between the Joint Institute for Nuclear Research (JINR) in Russia and the Lawrence Livermore National Laboratory (LLNL) in the United States. This new element was named after the Japanese word, Nihon, which means Japan, in honor of the contribution of Japanese scientists in the discovery of new elements.
Group and Period in the Periodic Table
Nihonium belongs to the Boron family, which is also known as Group 13 (IIIA) of the periodic table. The Boron family has three valence electrons in the outermost shell and is found in the p-block of the periodic table.
Nihonium belongs to the period 7 of the periodic table, which means that it has seven electronic shells or energy levels.
Block in the Periodic Table
As mentioned, Nihonium is an element in the Boron family, which is found in the p-block of the periodic table. The electronic state of Nihonium is not completely known yet.
However, based on its position in the periodic table, it is expected to be a metallic solid at room temperature.
Atomic Number and Weight
Nihonium has an atomic number of 113, which means it has 113 protons in its nucleus. Its atomic weight is around 284 atomic mass units, which is why Nihonium is classified as a heavy metal.
Electronegativity, Density, Melting and Boiling Points, Van der Waals and Ionic/Covalent Radii
The electronegativity of Nihonium is expected to be low, similar to the other elements in the Boron family. The density of Nihonium is expected to be high due to its heavy atomic weight, and its melting point and boiling point are expected to be relatively low compared to other heavy metals.
The Van der Waals radius of Nihonium is not yet known, but its ionic radius is expected to be smaller than its covalent radius due to its tendency to lose electrons.
Isotopes
Nihonium has been produced through the synthesis of various isotopes of Nihonium, such as Nh-286, Nh-287, and Nh-288. These isotopes are highly unstable and have very short half-lives, which means that they decay quickly and are not present naturally on Earth.
Electronic Shell and Configurations
The electronic shell and configurations of Nihonium follow the same Aufbau principle and Hund’s rule as other elements in the periodic table. However, due to its high atomic number, the electronic configurations of Nihonium are expected to be quite complex.
For instance, the electronic configuration of the ground state of Nh-284 is expected to be [Rn] 5f14 6d10 7s2 7p1.
Energy of Ionization
The energy of ionization is the energy required to remove one electron from an atom. Nihonium has not been experimentally studied enough yet to determine its energy of ionization accurately.
However, theoretical predictions suggest that its energy of first ionization is relatively low, indicating that it is relatively easy to remove an electron from a Nihonium atom.
Oxidation States
The oxidation states of Nihonium are predicted to be +1 or +3, based on the electron configurations of the elements in the Boron family.
Chemical Classification and State
Nihonium is classified as a transactinide element, which means it is a synthetic element that belongs to the superheavy elements category. It is a heavy, radioactive solid that is not present naturally on Earth.
It is produced in the laboratory by combining lighter isotopes with a target element through nuclear fusion.
Conclusion
Nihonium is one of the newest and rarest elements in the periodic table. Its properties and characteristics are still in the process of being studied and analyzed.
However, based on current theoretical predictions, Nihonium is a highly unstable, heavy metal that belongs to the Boron family, has a low electronegativity, a high density, and a low melting and boiling point. These properties make it a unique element that offers many opportunities for further scientific research and exploration.
Magnetic Properties
Nihonium is a synthetic and rare element with many unique properties, including its magnetic properties. As an element in the Boron family, Nihonium has three valence electrons in its outermost energy level.
This leads to the presence of unpaired electrons which gives Nihonium its paramagnetic property.
Paramagnetism
Paramagnetic elements have unpaired electrons that can align with external magnetic fields, creating a weak induced magnetic field. This alignment is due to the action of the magnetic dipole moment of unpaired electrons.
The number of unpaired electrons present in an element significantly contributes to the paramagnetic property. In Nihonium, the presence of unpaired electrons in its valence shell allows it to have a paramagnetic property.
The unpaired electrons can form magnetic domains that can align with an external magnetic field, causing the element to become weakly magnetic. The magnetic domains allow for Nihonium to attract to a magnetic field.
Naming and Origin
Discovery and Naming
In 2003, a livermore-Russia collaboration team synthesized Nihonium in Dubna, Russia, using a nuclear fusion process. Its discovery made it one of the latest elements to be synthesized in the periodic table.
The name Nihonium was proposed to honor Japan which played an essential part in the discovery of the element otherwise known as the island of the rising sun. When discovered, it was commonly referred to as Element 113 till its approval in 2016 by the IUPAC for its inclusion in the periodic table.
CAS Number and ChemSpider ID
A CAS number is a unique identifier given by the Chemical Abstracts Service to chemicals for easy identification. The CAS number for Nihonium is 54084-26-3.
Besides, the ChemSpider ID, an open database of chemical compounds also provides unique identifiers of chemicals along with their properties. The ChemSpider ID for Nihonium is 58848.
Nihonium’s CAS number and ChemSpider ID are essential for accurate identification in chemistry research. Many research experiments, especially those focused on Nihonium, employ these identifiers as criteria for accuracy.
Conclusion
In summary, Nihonium is a rare and synthetic metal with unique magnetic properties due to its unpaired electrons and location in the periodic table. Its discovery, naming, and identification by CAS number and ChemSpider ID are vital in studying and identifying the element accurately.
The continued scientific study of Nihonium presents groundbreaking opportunities in modern physics and chemistry, including further understanding of the fundamental building blocks of matter. In conclusion, Nihonium is a rare, synthetic element with unique properties such as paramagnetism.
Its discovery, naming, and identification through CAS numbers and ChemSpider IDs are crucial aspects of studying this element accurately. Understanding Nihonium offers a deeper understanding of the fundamental aspects of matter and the universe.
In summary, Nihonium is a groundbreaking element with remarkable properties that continue to intrigue scientists worldwide. FAQs:
