Rn Radon – Element Information, Facts, Properties, Trends,Uses, Comparison with other elements

Radon History

The element Radon was discovered by Friedrich Ernst Dorn in year 1900 in Germany . Radon derived its name From radium, as it was first detected as an emission from radium during radioactive decay

Radon Presence: Abundance in Nature and Around Us

The table below shows the abundance of Radon in Universe, Sun, Meteorites, Earth's Crust, Oceans and Human Body.

Crystal Structure of Radon

The solid state structure of Radon 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)

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

The positions of the atoms inside the unit cell are described by the set of atomic positions ( x_i, y_i, z_i) 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 Radon - neutral Radon atom

The ground state electronic configuration of Neutral Radon atom is [Xe] 4f14 5d10 6s2 6p6. The portion of Radon configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [Xe]. 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 4f14 5d10 6s2 6p6, electrons in the outermost shell that determine the chemical properties of the element.
