Symbol: PtAtomic Number: 78Atomic Weight: 195.084Classification: change metalPhase at Room Temperature: SolidDensity: 21.45 grams per centimeter cubedMelting Point: 1768°C, 3215°FBoiling Point: 3825°C, 6917°FDiscovered by: peoples of southern AmericaPlatinum is the third element of the tenth pillar in the periodic table. That is classified as a change metal. Platinum atoms have actually 78 electrons and 78 protons through 117 neutron in the many abundant isotope. That is considered to it is in a precious metal together with silver and gold.Characteristics and PropertiesUnder standard conditions platinum is a shiny, silvery metal. It is an extremely ductile, meaning that it have the right to be conveniently stretched right into a wire. That is additionally malleable, meaning it have the right to be pounded into a thin sheet.Platinum is resistant come corrosion when it come into call with air. It is also really dense (one the the greatest of the elements) and has a high melt point.Platinum is relatively inactive, however it will certainly dissolve in warm alkalis and aqua regia.Where is it discovered on Earth?Platinum is a rare steel and daunting to find. This is what provides it such a an important metal. Platinum can be uncovered in that is pure form, yet is most regularly found along with other metals from the platinum group. The bulk of platinum is mined in southern Africa with Russia comes in a remote second.

How is platinum provided today?
Being a priceless metal, platinum is frequently used as currency and as one investment. That is likewise used in coins and also to do jewelry such together rings, earrings, and also watches.Despite gift a renowned metal for jewelry, platinum is most often used together a catalyst in chemistry reactions. That is provided as a catalyst for the automobile and petroleum industries.Other applications because that platinum incorporate alloys for unique metals, super strong magnets, medical instruments, and dental work.How was it discovered?Platinum was an initial found by the peoples living in southern America prior to the arrival of the Spanish. They developed a platinum and gold alloy the they used in their artwork and jewelry.The first scientist to isolate platinum in that is pure element form was English chemist william Hyde Wollaston in 1803.Where walk platinum obtain its name?Platinum gets its name from the Spanish indigenous "platina" which means "silver."IsotopesThere are six naturally developing isotopes. The many abundant of this is Platinum-195.Interesting Facts around PlatinumWilliam Hyde Wollaston additionally discovered the aspects palladium and rhodium.It is the many ductile of the pure metals. Only gold is more malleable.The team of steels that platinum is component of in the regular table is sometimes called the platinum group.Its malleability allows it to be pounded into a sheet together thin together 100 atoms.The word "platinum" is often linked with wealth and also value. Periodically awards called "platinum" room considered higher than "gold."
