Unveiling the Mysteries of Oganesson: A Rare Element’s Properties and Electronic Configuration

Oganesson: A Rare and Interesting Element

Have you ever heard of Oganesson? This element sits at the bottom of the periodic table in group 18, along with other noble gases such as helium, neon, argon, krypton, xenon, and radon.

However, what sets Oganesson apart from the other elements in this group is its unique properties and characteristics. What is Oganesson?

Oganesson is a synthetic element with the atomic number 118, which means that it has 118 protons in its nucleus. It was first synthesized in 2002 by a team of Russian and American scientists led by Yuri Oganessian, for whom the element is named after.

Being a transactinide element, Oganesson is highly unstable and has a very short half-life of less than a second.

The Electronic Configuration of Oganesson

The electronic configuration of Oganesson is a fascinating area of study for chemists. It follows the Aufbau principle, which states that the electrons in an atom occupy lower energy orbitals before higher energy orbitals.

The Pauli exclusion principle states that no two electrons in an atom can have the same set of quantum numbers, and Hund’s rule declares that each orbital in a sublevel must be singly occupied before pairing begins. Thus, the electronic configuration of Oganesson is as follows:

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d10

This conveys that the 1s orbital is filled first with two electrons, then the 2s and 2p orbitals, until the 7s orbital is filled. The 4f and 5f orbitals are known as the f-block elements, and they are filled in a specific order as well.

Oganesson Structure and Characteristics

Oganesson is located in period 7 of the periodic table, which means it has seven energy levels. It is a p-block element, which indicates that the last electron enters the p orbital.

The element has a mass number of 294, and its symbol is Og. Its key isotope is 294 Og.

Oganesson has 176 neutrons and a highly positive electron affinity of 5.43 KJ mol -1. This makes it very reactive and unstable, with no stable isotopes currently known.

What makes the structure of Oganesson unique is its FCC centered cubic structure, which refers to the arrangement of atoms in a cube-like shape. This structure is highly stable and is found in metals such as copper, aluminum, and gold.

Despite the stability of this structure, no stable isotopes of Oganesson have yet been discovered.

Conclusion

Oganesson is a rare and fascinating element, with unique electronic configurations and structures that make it stand out among the other elements in the periodic table. While it may be unstable and highly reactive, it remains a promising area of study for chemists and scientists alike.

Oganesson Electronic Configuration Notations

When it comes to the electronic configuration of Oganesson, there are two different notations that can be used to represent how the electrons are arranged in the atom. These notations are abbreviated and unabbreviated electronic configurations.

Additionally, Oganesson’s electron configuration can change depending on whether it is in its ground state or an excited state.

Abbreviated Electronic Configuration

The abbreviated electronic configuration of Oganesson is often used to represent the elements in the p-block of the periodic table. Since Oganesson is found in period 7 and group 18, its abbreviated electronic configuration would be [Rn] 5f14 6d10 7s2 7p6.

This means that Oganesson’s valence electrons are in the 7s and 7p orbitals, as well as partially in the 5f and 6d orbitals. This notation is often used because it is more concise and easier to read than the unabbreviated electronic configuration.

Unabbreviated Electronic Configuration

The unabbreviated electronic configuration of Oganesson is a more detailed representation of how the electrons are organized within the atom. Oganesson’s unabbreviated electronic configuration can be represented as follows:

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d10 7p6

This notation represents Oganesson’s electrons in each orbital sequentially, starting from the 1s orbital and ending at the 7p orbital. This notation provides a more detailed understanding of the electronic configuration, but can be more difficult to interpret for those who are not familiar with chemistry jargon.

Ground State and Excited State Configuration

The electronic configuration of Oganesson is dependent on whether it is in its ground state or an excited state. The ground state of an atom is the most stable state, and has the lowest energy level possible.

In Oganesson, the ground state electronic configuration would be [Rn] 5f14 6d10 7s2 7p6.

However, in an excited state, Oganesson’s electronic configuration can change as electrons are promoted to higher energy levels, causing the atom to become unstable.

This excited state is not stable, and the electrons will rapidly return to their original ground state arrangement.

The Orbital Diagram of Oganesson

The orbital diagram of Oganesson is used to represent how the electrons are distributed into the atomic orbitals that are available. The diagram can be used to illustrate the energy levels of each orbital and the number of electrons that are found in each orbital.

In Oganesson, the electrons are distributed into the 7s, 7p, 5f, and 6d orbitals. The 7s orbital can hold up to 2 electrons, the 7p orbital can accommodate up to 6 electrons, the 5f orbital can hold up to 14 electrons, and the 6d orbital can hold up to 10 electrons.

The orbital diagram of Oganesson in its ground state would show a total of 118 electrons arranged in the following manner:

Conclusion

The electronic configuration of Oganesson is a fascinating area of study for chemists and scientists alike. Both the abbreviated and unabbreviated electronic configurations can be used to represent how the electrons are arranged in the atom.

In addition, the excited and ground state configurations of Oganesson can help illustrate its unique features. By examining the orbital diagram, the distribution of electrons in each orbital can be observed, providing a more detailed understanding of the element.

In conclusion, Oganesson is a synthetic and highly unstable element located at the bottom of the periodic table in group 18. Its electronic configuration can be represented in both abbreviated and unabbreviated forms, and its ground and excited state configurations can reveal unique properties.

Furthermore, the orbital diagram shows the electrons’ distribution in each orbital, providing a more in-depth understanding of the element’s electronic arrangement. Understanding the properties of Oganesson can help advance the study of the periodic table and its elements.
