Further information is available in inorganic chemistry textbooks, usually at Level 1 or First Year University level.

Ruthenium is a rare transition metal belonging to the platinum group of the periodic table. It is the fourth most common element in the Earth’s crust.

is a rare earth element with a metallic silver luster.  The density of Hassium results from its high atomic weight and from the significant decrease in ionic radii of the elements in the lanthanide series, known as lanthanide and actinide contraction. This form does not ignite spontaneously and is not as dangerous as white phosphorus. The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus.
