oganesson bohr model

The oganesson atom has seven electron orbits or shells which are located around the nucleus. These orbits have different radii. This element is placed in the group 18 of the periodic table which means that it belongs to the noble gas family.

This element was discovered by a joint research team from the Lawrence Livermore National Laboratory in California and the Joint Institute for Nuclear Research in Dubna, Russia in 2002. It is named after Russian nuclear physicist Yuri Oganessian who led the work on superheavy elements for many years.

Its atomic mass is 294 u. Its most stable isotope is 294Og, which has a half-life of 0.69 milliseconds.

Unlike other noble gases like xenon and neon, oganesson doesn’t have a shell structure on the outermost shell. Instead, it is surrounded by very dense electron shells that are almost indistinguishable.

This is because of the large relativistic effects on the atomic structure. The electrons’ spins are thrown out of their shell-like pattern and they end up scattered in all directions.

They calculate the electron configuration and ground-state energy as a function of internuclear distance R. The Bohr model gives remarkably close agreement with the exact potential curve and is much better than the Heitler-London result (see Fig. 9).

The ionization energies of this element are very low which is very surprising considering the fact that it is a member of the noble gas family. In fact, this element has the lowest ionization energy of any element in the periodic table.
