How to Locate Oganesson on Periodic Table

Periodic table is arranged by atomic number, number of protons in the nucleus which is same as number of electrons. The atomic number increases from left to right. Periodic table starts at top left ( Atomic number 1) and ends at bottom right (atomic number 118). Therefore you can directly look for atomic number 118 to find Oganesson on periodic table.

Another way to read periodic table and locate an element is by using group number (column) and period number (row). To locate Oganesson on periodic table look for cross section of group 18 and period 7 in the modern periodic table.

Oganesson History

The element Oganesson was discovered by Yuri Tsolakovich Oganessian in year 2006 in Russia and United States. Oganesson was first isolated by in . Oganesson derived its name from Yuri Oganessian, physicist.

Crystal Structure of Oganesson

The solid state structure of Oganesson is Face Centered Cubic.

The Crystal structure can be described in terms of its unit Cell. The unit Cells repeats itself in three dimensional space to form the structure.

Unit Cell Parameters

The unit cell is represented in terms of its lattice parameters, which are the lengths of the cell edges Lattice Constants (a, b and c)

abc

and the angles between them Lattice Angles (alpha, beta and gamma).

alphabetagamma

The positions of the atoms inside the unit cell are described by the set of atomic positions ( xi, yi, zi) measured from a reference lattice point.

The symmetry properties of the crystal are described by the concept of space groups. All possible symmetric arrangements of particles in three-dimensional space are described by the 230 space groups (219 distinct types, or 230 if chiral copies are considered distinct.

Ground State Electronic Configuration of Oganesson - neutral Oganesson atom

Abbreviated electronic configuration of Oganesson

The ground state abbreviated electronic configuration of Neutral Oganesson atom is [Rn] 5f14 6d10 7s2 7p6. The portion of Oganesson configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [Rn]. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used. This is important as it is the Valence electrons 7s2 7p6, electrons in the outermost shell that determine the chemical properties of the element.

Electrons are filled in atomic orbitals as per the order determined by the Aufbau principle, Pauli Exclusion Principle and Hund’s Rule.

  • As per the Aufbau principle the electrons will occupy the orbitals having lower energies before occupying higher energy orbitals. According to this principle, electrons are filled in the following order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p…
  • The Pauli exclusion principle states that a maximum of two electrons, each having opposite spins, can fit in an orbital.
  • Hund's rule states that every orbital in a given subshell is singly occupied by electrons before a second electron is filled in an orbital.
