Meitnerium

Introduction

Meitnerium (Mt) mainly has 7 isotopes that are denoted as the half-life. The key isotopes of the elements can be written as $\mathrm{{276}_{Mt}}$. The relative atomic mass of these elements which generates radiation is 277. The element behaves like a solid at 20°C which can be determined as the room temperature. Meitnerium (Mt), is the element that can be found in the d-block of the periodic table and in group 9. A cubic and crystalline structure proves that Meitnerium (Mt) has similarity with iridium. The element has the atomic radius of 128 pm. The density of Meitnerium (Mt) is written as 37.4 g cm³.

What is Meitnerium?

The element Meitnerium (Mt), is determined as the synthetic and radioactive element that is the more component of the modern periodic table. The elements are generally created in the laboratory and cannot be found in nature. Mt is the minor component of the periodic table with an atomic number 109.

Meitnerium (Mt) remain solid at room temperature and has 7 isotopes determined as its half-lives. It is the most stabilized metal that is depicted in the periodic table as meitnerium-278 (278Mt). Mt has an atomic mass of 277 g.mol^-1, and was discovered by the physicist Gottfried Münzenberg and Peter Armbruster in the year 1982.

Isotopes of Meitnerium Element

Meitnerium (Mt) is an element that is not present in nature and due to this it does not has any stable isotopes that form naturally. The elements are created in a laboratory and are very expensive. Presently, it has been found that Mt has 8 isotopes in total including 266, 268, 270 and 274-278. The isotopes of Meitnerium (Mt) are finely listed in the table below.

Occurrence of Meitnerium

The first discovery of Meitnerium (Mt), was done by famous physicists Gottfried Münzenberg and Peter Armbruster in the year 1982. The element was then discovered at Heavy Ion Research Laboratory situated in Darmstadt, Germany. The inventors bombarded the atoms of bismuth-209, with iron-58 ions in the linear accelerator. After this experiment, the atoms of meitnerium-266 were derived which have free neutrons. The element is not present freely in the environment and is required to create in the laboratory. The elements have the synthetic phase at their STP.

Mt has an atomic mass of 268 u, and 62.91367 u, which is its nuclear state if present in ground particles. Meitnerium is the minor element of the periodic table has the 109^th position and is denoted by symbol Mt. It remains as the metal that shows transitions consisting of 109 electrons as depicted in its electronic configuration.

Properties of Meitnerium

In the laboratory, this element has a lower production rate as it is very costly. The exact properties of these elements are still unknown and the probable properties are mentioned below.

• Meitnerium (Mt), is denoted as the seventh member that belongs to the 6 d series of metals that process transitions.

• The elements are also referred to as copernicium which has the element number 112. Copernicium is also denoted as a metal that generally belongs to group 12 (Neve, 2022). After evaluating this case, it can be stated that the properties of the elements are predicted to have an element number which ranges from 104 to 111.

• Copernicium element number range generally exhibits the physical or chemical properties of the 4th metal that processes transitions.

• Meitnerium (Mt), can also be determined as the part of platinum group metals and part of the 104 to 111 element series.

• After scientific research on this element, it has been found that Meitnerium (Mt), can also resemble the elements of group 9. The elements like cobalt, iridium and rhodium show similar properties to Meitnerium (Mt).

Uses of Meitnerium

Meitnerium (Mt) is determined as the element that has a higher rate of radiation and possesses transitions. The elements are referred to as minor metal in the modern periodic table which remains in a solid state at room temperature. Presently, this element has no uses as it is not freely available in nature. Mt has less production rate and is expensive if created in a laboratory. Meitnerium (Mt) is highly utilized in chemical research, including various technological mechanisms and harvesting energy.

Conclusion

Meitnerium (Mt), includes specific physical and chemical properties which are denoted as the rare and minor element that is unavailable in nature. The element highlights a remarkable rate of decay that gets solidified at room temperature that is 20°C. The group 9 metal of the modern periodic table, Meitnerium (Mt), was invented in the year 1982 by famous physicists Gottfried Münzenberg and Peter Armbruster.
