What is a platinum atom?

Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name is derived from the Spanish term platino, meaning “little silver”. Platinum is one of the least reactive metals.

When was platinum first discovered?

1735
Platinum/Discovered
The name is derived from the Spanish platina, meaning “silver.” Platinum was discovered in South America independently by Antonio de Ulloa in 1735 and by N. Wood in 1741, but it had been in use by pre-Columbian Indians.

Why is platinum so rare?

Platinum is much rarer than both gold and silver — so rare, in fact, that all of the platinum ever mined could fit into your living room. The vast majority of platinum comes from South Africa, where impediments to mining it have a strong impact on the spot price. These impediments have been coming fast and furious.

What is platinum made of?

Platinum also may be found as a byproduct of processing other metals like nickel and copper. Most platinum is derived from a mineral called cooperite, also known as platinum sulfide. Platinum is even found in outer space.

Is platinum good for health?

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.

Why is platinum so important?

Platinum is widely used as a catalyst for chemical reactions. The most important use of platinum is in vehicles, as a catalytic converter, facilitating the complete combustion of unburned hydrocarbon passing through the exhaust. Platinum is used in jewelry, decoration and dental work.

Can I wear platinum daily?

Platinum is extremely durable and strong making it ideal for jewellery that’s worn on a daily basis. It’s highly resistant to stress and withstands both extreme heat and extreme cold, which means platinum jewellery will retain its good looks better than any other metal.

Is platinum safe to eat?

When ingested or inhaled, platinum metal and insoluble salts are very poorly absorbed (<1% of a dose) and cleared from the body within a week after a single dose. Most absorbed platinum accumulates in the kidneys and is excreted in urine (Moore et al., 1975a, 1975b).

What is the atomic structure of platinum?

Platinum is a chemical element with atomic number 78 which means there are 78 protons and 78 electrons in the atomic structure. The chemical symbol for Platinum is Pt.

What is the atomic number of platinum?

The atomic number of the element Platinum is 78

What is the radius of the platinum atom?

Platinum crystallizes with the face-centered cubic unit cell. The radius of a platinum atom is 139 pm. Calculate the edge length of the unit cell and the density of platinum in.

What are the elements in platinum?

Platinum: description. Ruthenium, rhodium, palladium, osmium, iridium, and platinum together make up a group of elements referred to as the platinum group metals (PGM).
