It is extremely resistant to tarnishing and corrosion (which makes it known as a "noble metal") and is very soft and malleable, making it easy to shape; ductile, making it easy to stretch into wire; and unreactive, which means it doesn't oxidize and is unaffected by common acids. Stay up to date on the coronavirus outbreak by signing up to our newsletter today. It is highly malleable and ductile metal. It is more valuable and rare metal than silver and gold. ", In 1741, British scientist Charles Wood published a study introducing platinum as a new metal and described some of its attributes and possible commercial applications, according to Peter van der Krogt a Dutch historian. Because cancerous cells divide very rapidly, they need an excess of nourishment (such as glucose or folic acid), and these targeting systems can search the body for these various traits and deposit the medications directly within the cells, the authors said. Extremely valuable interstellar trading … These metals are often used together to create highly durable parts for various machines, tools and jewelry. Classified as a transition metal, Platinum is a solid at room temperature. Platinum is classified as a transition metal in the periodic table.
Photo from. In 1844, Michele Peyrone, an Italian chemist, accidently discovered that platinum has anti-neoplastic properties (which means it prohibits the development of tumors, according to MedicineNet).

Today, about 50 percent of cancer patients receive treatments that include this rare metal, according to a 2016 article published in the journal Chemical Reviews. Platinum hoort bij de platinagroep en is groep 10 van het periodiek systeem der elementen. Samples containing platinum are dissolved in aqua regia, are separated from the rest of the solution and byproducts, and are melted at very high temperatures to produce the metal. Het is een zwaar, buigzaam, kneedbaar, niet reactieve, kostbaar grijs-wit overgangsmetaal. Since platinum is not a reactive element, which makes it available in its pure form in nature. Platinum is found in nature alloyed with the other metals of the so-called platinum group, found in Group 10 of the periodic table periodic table, chart of the elements arranged according to the periodic law discovered by Dmitri I. Mendeleev and revised by Henry G. J. Moseley. It is the second most ductile metal after the gold. About 50 percent of cancer therapy patients currently use platinum-containing drugs, according to a 2014 study by Johnstone, Park, and Lippard Some of these drugs, such as cisplatin, are also used to treat tumors and cancer in animals, according to, Platinum is also used in pacemakers, dental crowns, and other equipment used within the human body because of its resistance to corrosion from bodily fluids and lack of reactivity to bodily functions, according to, The majority (about 80 percent) of platinum is mined in South Africa.

Platinum mine at South Africa. De Premium Access-overeenkomst van uw team verloopt binnenkort. Platinum was first discovered by William Hyde Wollaston. (He originally wrote it in 1735, but his papers were confiscated by the British navy. The authors call this a "dual threat" — platinum-containing drugs within a platinum-delivery system. The article discussed some of the next-generation platinum-containing cancer drugs and delivery systems that they say will be more effective in fighting cancer cells. They were wrong. It is located in 10th column and 3rd row of the periodic table. For example, platinum is used in the development of anti-cancer drugs. © South Africa supplies about 68% of total platinum produced in the world. In the early 1800s, friends and colleagues William Hyde Wollaston and Smithson Tennant, both British chemists, produced and sold purified platinum that they isolated using a technique developed by Wollaston, according to van der Krogt This technique involves dissolving platinum ore in a mixture of nitric and hydrochloric acids (known as aqua regia). The international prototype kilogram is a cylinder of platinum and platinum-iridium alloy, which is kept at the International Bureau of Weights and Measures (BIPM) near Paris. Due to the large amount of platinum needed to study these anticancer drugs, refining companies were eager to become involved very early on, as described by the authors. Future US, Inc. 11 West 42nd Street, 15th Floor, These drugs include cisplatin, carboplatin and oxaliplatin, and several others in trial stages. The worldwide production of platinum is about 160 tons.

These properties lead to many uses for this very rare and precious metal. Astronomers claimed galaxy was 98% dark matter. Approximately 10 percent is mined in Russia, and the rest is found in North and South America, according to the, Nearly 14 times more gold than platinum is mined per year — about 1,800 tons (1,633 metric tons) of gold compared to 130 tons (118 metric tons) of platinum, according to, Platinum combined with cobalt creates strong, permanent magnets, according to, Platinum is often used as a catalyst in the production of several solutions and byproducts (that end up in substances such as fertilizers, plastics and gasoline and in fuel cells, increasing their efficiency according to.
