What are the six platinum group metals?
The catalytic properties of the six platinum group metals (PGM)– iridium, osmium, palladium, platinum, rhodium, and ruthenium – are outstanding. Platinum’s wear and tarnish resistance characteristics are well suited for making fine jewelry.
What are the PGMs?
Platinum and the Platinum Group Metals (PGMs) The platinum group metals (PGM) comprise six precious transition metals—ruthenium, rhodium, palladium, osmium, iridium and platinum—which are each rare and highly valuable. They all have similar physical and chemical properties being highly unreactive silvery-white metals.
What is platinum’s family name?
Platinum is a silvery metallic chemical element, a member of the six transition elements in Group VIII of the periodic table known collectively as the platinum metals (ruthenium, rhodium, palladium, osmium, iridium, and platinum).
What is Group 10 on the periodic table called?
Group 10: Transition Metals.
Is platinum a gem?
Platinum is the most valued precious metal; its value exceeds even that of Gold. It has a beautiful silver-white color, and, unlike Silver, does not tarnish. Platinum jewelry is usually 90 to 95 percent pure. …
Is gold a PGM?
Over time, a number of interesting flowsheets have been developed for the concentration, separation, and purification of PGMs. Gold from this source is estimated to be some 5 t/year and is considered to be a by-metal with the six PGMs— namely, platinum, palladium, rhodium, iridium, ruthenium, and osmium.
What is a Platinoid?

What is Group 3 12 on the periodic table called?
Group 3-12: Transition and Inner transition metals group The elements lying from group 3 to 12 on the periodic table are named as Transition metals and Inner transition metals. The elements in the two bottom rows of the periodic table are also included in these groups.
What are periodic table trends in elements?
This is what is meant by periodicity or periodic table trends. There are multiple ways of grouping the elements, but they are commonly divided into metals, semimetals (metalloids), and nonmetals. You’ll find more specific groups, like transition metals, rare earths, alkali metals, alkaline earths, halogens, and noble gasses.
What are the columns and rows of the periodic table?
Groups and Periods are the columns and rows of the periodic table. In this section you will explore how the periodic table was put together and the two main arrangement of the periodic table focusing on the groups and periods and metals and non metals.
How do you classify elements on the periodic table?
There are multiple ways of grouping the elements, but they are commonly divided into metals, semimetals (metalloids), and nonmetals.
