Tennessine: The Short-lived Halogen with Nuclear Importance

Tennessine: The Heavy and Short-lived Synthetic Element

If you are a science enthusiast, you may find it fascinating to learn about new elements that have been discovered in recent years. One such element is Tennessine, a synthetic heavy element that is classified as a halogen and has an atomic number of 117.

Despite its short lifetime, Tennessine is an important element in nuclear reactions as it is the penultimate element of the seventh period in the periodic table. In this article, we will explore the properties and characteristics of Tennessine in greater detail.

Properties of Tennessine

Tennessine is represented by the symbol “Ts” and belongs to group 17 in the periodic table, also known as the halogen family. It has a melting point between 350-550 °C and a boiling point of 610 °C.

The atomic density of Tennessine is 7.3 g/cm3, and its atomic weight is 294 amu. The Van der Waals radius of Tennessine is not estimated, and the ionic/covalent radius is 156-157 pm.

Isotopes of Tennessine

Tennessine has two isotopes: 293Ts and 294Ts. Both of these isotopes are unstable and have very short lifetimes. Due to the unstable nature of Tennessine isotopes, their radioactive decay is highly unpredictable.

Electronic Shell and Configurations

The electronic shell of Tennessine consists of 2, 8, 18, 32, 32, 18, and 7 electrons. The element has a total of five energy levels, and its electron configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 4f14 5d10 6s2 6p6 5f14 6d10 7s2 7p5.

An energy level is a region around an atom’s nucleus where electrons are most likely to be found.

Oxidation States

Tennessine has four primary oxidation states: -1, +1, +3, and +5.

These oxidation states indicate how many electrons are lost or gained during a chemical reaction. The -1 oxidation state is uncommon, but the +1 and +3 states have been observed in some chemical compounds.

Chemical Classification

Tennessine is classified as a synthetic heavy element, a halogen, and an alpha decay element. Synthetic elements are created through artificial means, usually by bombarding lighter elements with atomic particles.

This process creates heavy elements that don’t exist in nature. Halogens are a group of elements in the periodic table that share similar chemical properties.

CAS Number and ChemSpider ID

The CAS number of Tennessine is 54101-14-3. However, a ChemSpider ID for Tennessine has not been found yet.

Allotropic Forms and Energy of Ionization

No allotropic forms of Tennessine have been discovered yet. The first ionization energy of Tennessine is 742.9 kJ/mol, the second ionization energy is 1435.4 kJ/mol, and the third ionization energy is 2161.9 kJ/mol.

These values indicate the energy required to remove one, two, or three electrons from a neutral atom of Tennessine.

State of Tennessine

At room temperature, Tennessine is in a solid state. This implies that Tennessine atoms are densely packed in a crystalline structure.

A critical characteristic of Tennessine is its paramagnetism, which is a measure of the level of attraction shown by the element towards external magnetic fields. Despite its significant role in nuclear reactions, the magnetic property of Tennessine is yet to be studied or discussed in detail.

Analyzing and Extracting Information

To gain a deeper understanding of the properties and characteristics of Tennessine, it is essential to analyze and extract information from the given topics and subtopics. To achieve accuracy, clarity, and flexibility in writing about Tennessine, it is imperative to consider the keywords associated with the element, such as “synthetic element,” “halogen family,” “periodic table,” and “atomic number.” These keywords are significant in understanding the position of Tennessine in the periodic table, its chemical properties, and the characteristics that differentiate it from other elements.

Additionally, analyzing the electronic shell and configuration of Tennessine provides insight into the element’s electron distribution and reactivity. The energy of ionization values indicates the strength of the attraction between the nucleus of the atom and its valence electrons. This is an essential feature in the determination of the element’s chemical and physical properties.

Accuracy and Clarity

It is crucial to maintain accuracy when writing about Tennessine and its properties. This requires careful cross-checking of data and information, especially considering that Tennessine was only discovered recently. In contrast, Clarity is a critical aspect of scientific writing as it ensures that readers can easily comprehend the concepts and ideas being conveyed. This may involve breaking down complex concepts into simpler terms, making use of illustrations and graphics, or providing definitions for technical terms.


Writing about Tennessine requires a certain level of flexibility to accommodate new and emerging information. Since the element is synthetic and not found in nature, researchers are continually discovering new facts and information about it. To capture these new discoveries and knowledge, it is crucial to be open-minded, remain updated, and make the necessary revisions to existing information.


In conclusion, Tennessine is an important synthetic element that plays a significant role in nuclear reactions due to its heavy and short-lived nature. It belongs to group 17, also known as the halogen family, in the seventh period of the periodic table.

Understanding the properties and characteristics of Tennessine requires careful analysis and extraction of information from the existing knowledge. Accuracy, clarity, and flexibility are essential factors in effectively conveying information about Tennessine and the scientific discoveries about it.
