Pure silver is nearly white, lustrous, soft, very ductile, malleable, it is an excellent conductor of heat and electricity. It is not a chemically active metal, but it is attacked by nitric acid (forming the nitrate) and by hot concentrated sulfuric acid.

What physical properties does platinum have?

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 …

What is the difference between sterling silver and platinum?

Alloys containing 92.5% silver is known as sterling silver and is the most commonly used. Fine silver, or 99.9% pure silver, is used in jewelry making but is very soft and not ideal for items such as rings. Platinum is generally combined with copper, palladium, cobalt, iridium and ruthenium.

Are platinum and silver atoms identical?

Two of the world’s most famous precious metals – platinum and silver – can appear identical to the untrained eye. They’re both shiny, metallic, and gray in nature, and at first glance, they don’t appear to have any intrinsic differences.

What is platinum mostly used for?

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.

Does platinum look like silver?

While at first glance both silver and platinum appear silver in color, the two metals are actually easily discernible to the naked eye. Both have gray undertones, unlike white gold which has a warmer, yellow undertone, but platinum is much brighter and shinier and silver has a duller, gray appearance.

What’s the difference between silver and platinum in color?

While at first glance both silver and platinum appear silver in color, the two metals are actually easily discernible to the naked eye. Both have gray undertones, unlike white gold which has a warmer, yellow undertone, but platinum is much brighter and shinier and silver has a duller, gray appearance .

What are the physical and chemical properties of platinum?

Artwork: The platinum group metals (with their periodic table data). Physically, platinum is heavy, soft, malleable (easy to work—only silver and gold are easier to shape), and ductile (easy to draw into wires) and has a fairly high melting point (~1770°C or 3220°F). Chemically, it’s often described as a noble metal because it is so unreactive.

Which is harder gold, silver, or platinum?

Silver has the greatest ability to transfer heat through its structure than any of the other metals. Gold has the greatest ability to be hammered and stretched into long and flat shapes before losing its structural integrity. Platinum is the hardest of the four precious metals.

What’s the difference between white gold and silver?

Both have gray undertones, unlike white gold which has a warmer, yellow undertone, but platinum is much brighter and shinier and silver has a duller, gray appearance. The difference in durability is really no contest between platinum and silver. Silver is a soft metal that wears down quickly and tarnishes easily.
