An alloy of platinum and cobalt is used to produce strong permanent magnets.

(Previously known metals included iron, copper, silver, tin, gold, mercury and lead. The first recorded reference to platinum was in 1557 when Julius Scaliger, an Italian physician, described a metal found in Central America that wouldn't melt and called it "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 Back in the 18th century, platinum was the eighth known metal and was known as "white gold," according to van der Krogt. Platinum is used in jewelry, decoration and dental work. Platinum metal became popular in such pieces due to its pale colour. Platinum is a soft, dense, ductile metal that is … In the course of his studies on platinum ores he also discovered the metals osmium, iridium, rhodium and palladium – the elements which had made Chabaneaus’ work so frustrating.The element name comes from the Spanish word ‘platina’ meaning little silver. © Royal Society of Chemistry 2020You do not have JavaScript enabled. These include BaPt, Archaeologists have discovered traces of platinum in the gold used in ancient Egyptian burials as early as 1200 BC. Classified as a transition metal, Platinum is a solid at room temperature. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f).The arrangements of electrons above the last (closed shell) noble gas.The temperature at which the solid–liquid phase change occurs.The temperature at which the liquid–gas phase change occurs.The transition of a substance directly from the solid to the gas phase without passing through a liquid phase.Density is the mass of a substance that would fill 1 cmThe mass of an atom relative to that of carbon-12. Element 78 of Periodic table is Platinum with atomic number 78, atomic weight 195.078.

It is more precious than silver but with prices more volatile than gold. This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores.The number of atoms of the element per 1 million atoms of the Earth’s crust.The percentage of a commodity which is recycled. Platinum was discovered by South American peoples who produced artifacts of a white gold-platinum alloy.

If not, here's Katherine Haxton.Platinum as a metal speaks of prestige, value and power. Members of a group typically have similar properties and electron configurations in their outer shell.A horizontal row in the periodic table.

A higher recycling rate may reduce risk to supply.The availability of suitable substitutes for a given commodity.High = substitution not possible or very difficult.Medium = substitution is possible but there may be an economic and/or performance impactLow = substitution is possible with little or no economic and/or performance impactThe percentage of an element produced in the top producing country. It is non-toxic. It is given by the ratio of the pressure on a body to the fractional decrease in volume.A measure of the propensity of a substance to evaporate. The elements all possess a silvery white colour—except osmium, which is bluish white. Some platinum is prepared as a by-product of copper and nickel refining.

By itself, it has various applications in photography, zinc etchings, Treatment of hexachloroplatinic acid with an ammonium salt, such as When hexachloroplatinic acid is heated, it decomposes through Several barium platinides have been synthesized in which platinum exhibits negative oxidation states ranging from −1 to −2. 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.It is also one of the densest elements at 12.4 ounces per cubic inch (21.45 grams per cubic centimeter), a little more than 21 times the density of water or 6 times the density of a diamond according to In ancient times, people in Egypt and the Americas used platinum for jewelry and decorative pieces, often times mixed with gold.

It has the third highest density, behind osmium and iridium . It does not oxidize in air even at high temperatures and is unaffected by common acids.
