Unraveling the Mystery of Oganesson: Atomic Structure and Properties

The Fascinating World of Oganesson: Understanding its Atomic Structure and Electron Distribution

Have you ever wondered what the largest element in the periodic table is? Enter Oganesson, with an atomic number of 118 and an atomic weight of 294.

This fascinating element was first discovered in 2002 and is named after Russian physicist Yuri Oganessian. Its short existence and limited properties make it a rare element, but nonetheless one that offers plenty of intrigue for chemists and scientists alike.

In this article, well take a closer look at the atomic structure and electron distribution of Oganesson.

Atomic Structure of Oganesson

One of the defining characteristics of any chemical element is its atomic structure. For Oganesson, this structure consists of 118 protons, 118 electrons, and 176 neutrons.

Protons, which have a positive charge, lie in the nucleus along with the neutrons, which are electrically neutral. Electrons surround the nucleus in electron shells.

One interesting fact about Oganesson is that it has 7 electron shells, which is more than any other element.

Distribution of Electrons in Oganesson

To understand how the electrons are arranged in Oganesson, its helpful to create a Bohr diagram. This is a model of an atom that shows the number of electrons in each shell.

The first electron shell contains 2 electrons, followed by the second shell, which can hold 8. The third shell can hold up to 18 electrons, while the fourth and fifth shells can hold 32 each.

The sixth shell can hold 18 electrons and the seventh shell, the outermost orbital, can hold up to 8 electrons. Why is Oganesson so heavy?

One question that immediately comes to mind is why Oganesson is so heavy. Most elements have atomic weights in the range of 1 to 100, but Oganessons atomic weight is closer to 300.

To answer this, we need to look at the number of neutrons in Oganesson’s nucleus. Its a known fact that elements with a higher number of neutrons are usually heavier.

Oganessons nucleus contains 176 neutrons, which is one of the reasons why its such a heavy element.

The significance of Oganesson

Oganesson doesnt have any known practical applications at the moment, but that doesnt diminish its significance in the field of chemistry. Scientists are constantly fascinated by its properties, and studying this element has the potential to unlock new insights into the periodic table.

Additionally, understanding the properties of elements with a higher number of protons and neutrons can help us gain insight into the fundamental nature of matter. In summary, Oganesson is one of the most intriguing elements we have discovered so far.

Its atomic structure, particularly its 7 electron shells, is remarkable, and its high atomic weight is a testament to its rarity and uniqueness. While it doesnt have any practical applications yet, its existence offers plenty of food for thought for scientists and chemists.

As we continue to study and explore the properties of Oganesson, we may uncover more surprises and insights into the mysteries of the universe.

Bohr Model of Oganesson

Danish physicist Niels Bohr developed a model of atomic structure in 1913, which is known as the Bohr model. This model describes the arrangement of electrons in an atom and the energy levels electrons can reside in.

The Bohr model is often used as a tool to help visualize and understand the electronic structure of an atom. In the case of Oganesson, the Bohr model provides us with some fascinating insights into the properties of this element.

Arrangement of Electrons

In the Bohr model of an atom, electrons are arranged in energy levels, similar to how planets orbit the sun in our solar system. Electrons occupy the lowest energy levels first, starting with the innermost shell.

In Oganesson, which has the highest atomic number of any known element, the electrons are arranged in a very unique way. With a total of 118 electrons, Oganesson has 7 electron shells, which means it has more electron shells than any other element.

Intriguingly, the electrons in Oganessons outermost shell are held very loosely. This makes them very vulnerable to external influences, such as radiation, which can dislodge them from their orbit.

This is important because it means that Oganesson is highly reactive, which is one of the reasons why it is so difficult to produce and study in the laboratory.

Energy Levels

In the Bohr model, energy is quantized, which means it can only take specific values. Each energy level in an atom has a specific energy value assigned to it, which relates to the distance of the electron from the nucleus.

The closer an electron is to the nucleus, the lower its energy and the higher its stability. Conversely, the further an electron is from the nucleus, the higher its energy and the lower its stability.

With seven electron shells, Oganesson has more energy levels than any other element. This is significant because it means that Oganesson has a high potential for chemical reactions as some portions of its electrons are barely stable and held very loosely as mentioned earlier.

Oganesson has an outermost energy level with up to eight electrons, making it very unstable and reactive.

Quantum Numbers

The Bohr model is also a useful tool for understanding quantum numbers, which help to describe the behavior and position of electrons in an atom. In the Bohr model, each electron shell is labeled with a principle quantum number, n, which indicates the energy level of the shell.

The maximum number of electrons that can occupy each shell is given by 2n^2. Oganessons electrons occupy all the orbits up to the seventh shell, making it the maximum number of shells to fill which brings the principle quantum number to seven.

Furthermore, each electron shell in Oganesson also has a unique set of quantum numbers, which describes the orientation and positioning of the electron within that shell.

Properties of Oganesson

Atomic Mass

Oganesson is the heaviest element on the periodic table to have been officially recognized. Its atomic weight is 293, which is significantly higher than other elements.

Oganessons atomic mass comes from the large number of neutrons in its nucleus, which are necessary to provide enough attractive force to hold the 118 protons together.


Oganesson is very unstable, which makes it challenging to produce and study in the laboratory. This is because its outer electrons are held very loosely and are vulnerable to radiation, which can dislodge them from their orbit.

In fact, Oganesson is so unstable that any samples produced during laboratory experiments tend to break apart rapidly, often within milliseconds.


Like many heavy elements, Oganesson is radioactive, which means it is constantly emitting radiation. Because of its instability, it has a very short half-life, which means that it decays very quickly.

The half-life of Oganesson is only a few milliseconds, which presents a significant challenge for scientists who wish to study the element in more detail. Despite its unstable nature, Oganesson has the potential to unlock new insights into the periodic table and the fundamental nature of matter.

As technology advances and the field of materials science develops, it is possible that the unique properties of Oganesson and other heavy elements will become increasingly relevant and useful.

Experimentation with Oganesson

Oganesson is one of the rarest and heaviest elements in the periodic table. Given its unique properties and the challenges involved in producing and studying it, experimentation with Oganesson has been a topic of interest for many researchers.


One of the primary challenges of experimenting with Oganesson is that it is incredibly difficult to synthesize. It was first discovered in 2002 by a team of Russian and American scientists, who produced the element by bombarding Californium-249 with calcium-48 ions.

Even with this method, the production of Oganesson is extremely low, and researchers typically have to wait years between each experiment to accumulate even small amounts of the element.


Most of the observation of Oganesson has been in supporting theoretical investigations, which include scientific studies and experiments related to its fundamental and chemical properties. Of course, immediate detection of the element is impossible due to their unstable nature.

However, mass spectrometry techniques, often used to determine the composition of any sample, has been utilized for observing and examining oganesson. Furthermore, the observations of Oganesson focus on the physical and chemical properties of the element.

Its reactivity and instability make it challenging to observe directly, but its electronic structure and atomic behavior have been studied in great detail. With the use of modern technology, scientists have been able to generate models that provide a visual representation of the element, as well as data on its binding energy, ionization potential, and other properties.

Applications and Uses

Currently, there are no practical applications for Oganesson as its scarcity and instability make it difficult to study and utilize directly. It is only commonly used in scientific investigation and testing of theoretical models.

However, there may be applications in the future as scientists learn more about the element and its properties and researchers are looking forward to utilizing Oganesson in various fields of study, particularly if its reactivity can be controlled and manipulated. One potential application of Oganesson could be in nuclear medicine.

Because of its high atomic weight, it is possible that oganesson could be used in cancer treatments, particularly in targeted radiation therapy. However, much more research is needed in this area before any conclusions can be drawn about the feasibility of such applications.

Another potential application could be in the field of materials science. With its heavy mass and unique electronic structure, Oganesson may play a role in the development of new materials for advanced technologies such as semiconductors, superconductors, and beyond.


In conclusion, Oganesson remains one of the most fascinating and mysterious elements on the periodic table. By synthesizing and studying oganesson, scientists can gain valuable insights into the nature of matter and the laws of the universe that govern the behavior of subatomic particles.

While experimentation with Oganesson is still in its early stages, the potential applications and uses for this rare and unique element are exciting to contemplate, and may open new doors to the experimentation of many untapped areas of research. In conclusion, the atomic structure and electron distribution of Oganesson, with its 118 protons, 176 neutrons, and 118 electrons arranged in 7 electron shells, make it a unique and intriguing element.

The Bohr model helps visualize its electron arrangement, energy levels, and quantum numbers. Oganesson’s heavy atomic mass and high reactivity pose challenges for experimentation, limiting its practical applications so far.
