What is the properties and uses of platinum?
Uses and properties A shiny, silvery-white metal as resistant to corrosion as gold. Platinum is used extensively for jewellery. Its main use, however, is in catalytic converters for cars, trucks and buses. This accounts for about 50% of demand each year.
What is special about platinum?
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. It is also ductile, making it easy to stretch into wire, and unreactive, which means it doesn’t oxidize and is unaffected by common acids.
What are the element properties?
All elements have properties. Those properties include, but are not limited to, conductivity, magnetism, melting point, boiling point, color, state of matter, and others. Elements with similar properties are grouped together in different areas of the periodic table of elements.
Why is platinum toxic?
The health effects of platinum are strongly dependent upon the kind of bonds that are shaped and the exposure level and immunity of the person that is exposed. Finally, a danger of platinum is that it can cause potentiation of the toxicity of other dangerous chemicals in the human body, such as selenium.
What are the dangers of platinum?
While the metal is non-toxic, platinum salts can be harmful for human health. They can cause hearing damage, bone marrow and kidney damage, cancer, and DNA alterations. Platinum salts also cause damage to the intestines and allergic reactions. Short-term exposure may cause irritation of the throat, nose, and eyes.
What are 3 interesting facts about platinum?
Platinum is a silver-white metal — it was once known as “white gold.” 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 wearing platinum good for health?
What are the two properties of an element?
These properties include color, density, melting point, boiling point, and thermal and electrical conductivity. While some of these properties are due chiefly to the electronic structure of the element, others are more closely related to properties of the nucleus, e.g., mass number.
Is platinum poisonous to humans?
Platinum toxicity has the ability to cause DNA alterations, cause cancer, allergic reactions of the skin and mucous membranes, it can cause damage to organs such as the kidneys and intestines and has been known to damage hearing ability.
What element is platinum used for?
According to The Royal Society of Chemistry, platinum is mainly used inside catalytic converters in cars, trucks, and buses. Platinum is also used for electrical components, thermocouple elements, corrosion-resistance apparatuses and dentistry.
What elements does platinum react well with?
Platinum metal does not normally react with air or oxygen. Reaction of platinum with water. Reaction of platinum with the halogens. Careful control of the reaction between platinum metal and fluorine gas, F2, results in either the volatile platinum(VI) fluoride , PtF6 or the tetrameric platinum(V) fluoride, (PtF5)4.
What is the normal phase of platinum element?
Normal phase? the atomic mass of platinum is 195.078. the atomic number is 78. the melting point is 1768.3 degrese celcius. the family is metal. Spanish explorers in 1538. the origin of the name comes from the name plata which means silver in spanish so platinum was called platina because it looked like silver.
Why is pure platinum an element?
Platinum’s purity also means that it is naturally hypoallergenic. Recognized as an element in the 18th century, scientists soon discovered that this unusual white metal, difficult to melt using traditional methods, was also nearly incorruptible by gases or chemicals making it thoroughly non-corrosive. Platinum is also extremely dense.
