Red salts are not typical of platinum, and Wollaston suspected something else was present in the sample. Rhodium powder is also commonly used in enterprise-level electronics components due to its ability to act as an electrical resistor when applied at lower temperatures and in thinner layers than competing materials which generally require higher temperatures resulting in longer production times. What's so special about rhodium plating? Their sample had secrets of its own hidden away a new, rare metal never known to science before then is, today, the most valuable and precious metal on the planet, rhodium, a chemical element with the symbol Rh and atomic number 45. Then a variety of chemicals are applied to the mixture followed by electrolytic deposition where electric currents are sent through solutions containing dissolved salts or other ions to cause tiny particles of metal to form on an electrode (in this case Rhodium) Once these have been cooled further they can then be alloyed with other metals like nickel or copper which create superior conductivity when producing complex circuits for electronic components such as smart phones, computers, cars etc. Rhodium was, for example, until recently the prime choice as catalysts in making one of mankind's oldest chemicals, acetic acid.

After precipitating the soluble solution, he noticed reddish salts remained. It provides a measure of how difficult it is to extend a material, with a value given by the ratio of tensile strength to tensile strain. Wollaston called the new metal rhodium, rooted in the Greek word for rose, "rhodon," because of the reddish salts that were dissolved in the aqua regia (aqua regia is a yellow-orange fuming liquid, so named by alchemists because it can dissolve the noble metals gold and platinum).
