Platinum Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. It has six naturally occurring isotopes. It is one of the rarer elements in Earth's crust with an average abundance of approximately 5 μg /kg.latinum has six naturally occurring isotopes: 190 Pt, 192 Pt, 194 Pt, 195 Pt, 196 Pt, and 198 Pt. The most abundant of these is 195 Pt, comprising 33.83% of all platinum.

What is platinum used for? Best Answer: Because of its chemical inertness and high fusing point, platinum is valuable for laboratory apparatus, such as crucibles, tongs, funnels, combustion boats, and evaporating dishes. Small amounts of iridium are usually added to increase its hardness and durability.latinum compounds are also used in medicine, with cisplatin being the first to be discovered, and carboplatin is a more recent anti-cancer drug. It is also used as a catalyst in many chemical reactions, such as car exhaust cleaners.

Shades of gray Platinum is a color that is the metallic tint of pale grayish-white resembling the metal platinum. This is supposed to be a metallic color; however, there is no mechanism for displaying metallic colors on a flat computer screen. The first recorded use of platinum as a color name in English was in 1918.

- In its pure form, the element is very hard to machine and very brittle. The main application of iridium is as a hardening agent of platinum. High temperature equipment such as crucibles is made from platinum-iridium alloys.Alloys made of osmium and iridium are used to produce elements of fountain pens.Given that this element is corrosive-resistant, an alloy of 10 percent iridium and 90 percent platinum was used to create the standard meter bar.n its pure form, the element is very hard to machine and very brittle. The main application of iridium is as a hardening agent of platinum. High temperature equipment such as crucibles is made from platinum-iridium alloys.

- The metal is rapidly attacked by fused alkali oxides and by peroxides and will react with fluorine and, at red heat, with chlorine. On heating, platinum combines directly with elemental phosphorus, silicon, lead, arsenic, antimony, sulfur, and selenium, a fact that influences the use of platinum laboratory equipment. In keeping with the other members of the platinum group, the metal shows a fairly strong tendency to form complex ions.

- Platinum is found uncombined in alluvial deposits. Most commercially produced platinum comes from South Africa, from the mineral cooperite (platinum sulfide). Some platinum is prepared as a by-product of copper and nickel refining.

- Palladium is also used in electronics, dentistry, medicine, hydrogen purification, chemical applications, groundwater treatment and jewelry. Palladium plays a key role in the technology used for fuel cells, which combine hydrogen and oxygen to produce electricity, heat, and water.alladium is a soft silver-white metal that resembles platinum. It is the least dense and has the lowest melting point of the platinum group metals. It is soft and ductile when annealed and greatly increases its strength and hardness when it is cold-worked.

What Is Palladium? Palladium is also used in jewelry, starting in 1939 when its sister metal platinum was reserved for military use. One benefit of palladium for jewellers was that palladium was lighter than platinum so larger jewelry pieces could still be comfortable.alladium is a precious metal that is about 30 times as rare as gold. It is a natural white metal that has a luster similar to platinum, another precious metal. Palladium is strong, durable and will last a long time without wear.

History of PGM In Canada in 1888, platinum was discovered in the nickel-copper ores of Ontario. Between the end of the First World War and the 1950s, Canada was the world's major source of supply. In 1924 a farmer in the Transvaal province of South Africa discovered several nuggets of platinum in a riverbed.etween the end of the First World War and the 1950s, Canada was the world's major source of supply.

Platinum Uses: Modern Applications Platinum Uses: Modern Applications. The reason why platinum is today the most valuable of precious metals is because it is required in so many industrial applications. It is estimated that one-fifth of everything we use either contains platinum or requires platinum in its manufacture.Among all the known modern uses of platinum, most of the annual production is consumed by two dominant categories-catalytic converters and fine jewelry.t is estimated that one-fifth of everything we use either contains platinum or requires platinum in its manufacture.

The uses of Silver Silver was one of the earliest metals used to make coins. The Romans used silver in this way as early as 269 BC (more than 2000 years ago). Mexico is the only country today that uses silver in its circulating coinage.

- Nearly all spark plug manufacturers use platinum in one form or another on their long life or performance spark plugs. This is due to platinum’s high melting point, which makes it useful in two ways: - On long life spark plugs a thin wafer of platinum is bonded at the firing point to the center electrode (and possibly ground electrode) solely so they don’t wear as fast as a traditional plug.

How long will fresh spinach last in the fridge before it does bad? What is its shelf-life? Relevance. Rating Newest Oldest. Best Answer: well it depends on how fresh it was when you bought it. If it has no brownish tint to it and its not in s slimy feeling, and it still smell good then it should be fine. Another way to see if it is good is to taste it, and if it tastes yukky then don't eat it.

Something Rare In The Air: Osmium Some 95 percent of the world’s platinum comes from South Africa and Russia where it's roasted at extremely high temperatures during extraction and refinement. The heat turns the sulfur in the ore into sulfur dioxide and releases osmium. Neither country has environmental regulations for the process.

A Brief History of Gold Gold was the first metal widely known to our species. When thinking about the historical progress of technology, we consider the development of iron and copper-working as the greatest contributions to our species' economic and cultural progress-but gold came first.

Metal The best-known precious metals are gold and silver. While both have industrial uses, they are better known for their uses in art, jewelry, and coinage. Other precious metals include the platinum group metals: ruthenium, rhodium, palladium, osmium, iridium, and platinum, of which platinum is the most widely traded.strophysicists use the term metal to collectively describe all elements other than hydrogen and helium. Thus, the metallicity of an object is the proportion of its matter made up of chemical elements other than hydrogen and helium.
