Welcome to the periodic table of the elements powered trail; which begins at Mount Henry Bridge and continues south down the freeway cycle path. Please stay safe and enjoy the power trail.
08/10/2018 Update: the Periodic Table series has been adopted by multiple volunteers.
The periodic table of elements are those approved by the International Union of Pure & Applied Chemistry.
Palladium is a steel-white metal, does not tarnish in air, and is the least dense and lowest melting of the platinum group metals. When annealed, it is soft and ductile. Cold working increases its strength and hardness. It is used in some watch springs. At room temperature the metal has the unusual property of absorbing hydrogen up to 900 times its own volume. Hydrogen readily diffuses through heated palladium, providing a means of purifying the gas.
Ruthenium, rhodium, palladium, osmium, iridium, and platinum together make up a group of elements referred to as the platinum group metals (PGM). Source: Webelements
