What element family is rhodium in?
What element family is rhodium in?
platinum group metals
Rhodium, together with ruthenium, palladium, osmium, iridium, and platinum form a group of elements referred to as the platinum group metals (PGM).
What is the group name of rhodium?
platinum metals
rhodium (Rh), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table, predominantly used as an alloying agent to harden platinum.
Where is rhodium in the periodic table?
Chemical properties Rhodium belongs to group 9 of the periodic table, but the configuration of electrons in the outermost shells is atypical for the group.
What are Group 9 elements called?

What is rhodium in?
These alloys appear in items such as furnace coils, aircraft engines, electrodes for aircraft spark plugs, and laboratory crucibles. The most common use for rhodium, though, is in vehicles’ catalytic converters, either as a standalone element or in tandem with palladium or platinum.
What rhodium means?
Definition of rhodium : a rare silvery-white hard ductile metallic element that is resistant to acids, sometimes occurs naturally in pure form but is usually obtained from nickel ores, and is used especially as a catalyst and in platinum alloys — see Chemical Elements Table.
Is rhodium a rare earth metal?
Rhodium is an extremely rare precious metal. Rhodium, one of six PGMs, is a silver-white metallic element that is highly reflective and strongly resistant to corrosion. It is considered the rarest and most valuable precious metal in the world — far more so than gold or platinum.
What is Group 10 called in the periodic table?
Transition Metals
Group 10: Transition Metals.
What is the family of silicon?
metalloids family
Silicon: the in-between element praised for its flexibility Ranked between metals and non-metals in the periodic table, silicon (Si) belongs to the metalloids family. Silicon is the most abundant element in the Earth’s crust after oxygen (O) but it does not naturally exist in a free state on Earth.
Is rhodium a gold?
Rhodium is a fine metal, just like gold or platinum, and is a member of the platinum family of metals. It has a bright, silvery-white appearance and is naturally corrosion resistant. Its purity also makes it hypoallergenic (which is great for those folks who might have silver or nickel allergies).
What is rhodium made out of?
Commercial rhodium is generally obtained as a byproduct of copper and nickel refining. In nature, rhodium can occur uncombined or with other platinum minerals. It can be found in river sands in North and South America and in copper-nickel sulfide ores in Ontario, Canada, according to the Royal Society of Chemistry.
