Why is platinum dense?

Thats due to higher impurities in found platinum. The unit cell of gold is larger and that follows exactly with the density if both have the same crystal structure. So pure platinum is higher density than gold. The Mindat says gold density is 15 to 19.3 g/cc and platinum is 14 to 19 g/cc as found in nature.

Is platinum a dense metal?

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 Chemicool. These properties lead to many uses for this very rare and precious metal.

Is platinum very dense?

1. What’s the difference between platinum and white gold? As one of the most precious metals, platinum alloys are 90\%-95\% pure. Platinum is also so dense that a six-inch cube would weigh about 165 pounds.

Why is platinum so inert?

Platinum is one of the “noble” metals that is known for being highly unreactive. Platinum is so stable that it cannot even be attacked by most acids – only the strongest acid solutions, such as aqua regia (a mixture of anhydrous nitric and hydrochloric acids) can cause it to react.

What is the density of platinum?

21.45 g cm-3
Platinum is an element with atomic symbol Pt, atomic number 78, and atomic weight 195.09. Silvery, whitish-gray, malleable, ductile metal. Mp: 1772°C; bp: 2187°C. Density: 21.45 g cm-3 at room conditions (very dense).

Which is more dense gold or platinum?

As a guide, comparative weight differences work out as follows. Platinum is approx 88\% heavier than 9ct Gold. Platinum is approx 34\% heavier than 18ct Gold. Platinum is approx 11\% heavier than Fine Gold.

Is platinum soft or hard?

Platinum is not a hard metal. It is 4 – 4.5 on the MOHs scale of hardness. This means it can be scratched by anything harder than it is. Diamond is ten on the MOHs scale and can easily scratch platinum.

Is platinum denser than silver?

Platinum Is Heavy! Yet the fact is, platinum is heavier than either gold or silver. It is about 60\% heavier than gold, which is a pretty heavy metal too. And gold, depending on its karat rating (and what other metals are mixed with it) is about 30\% heavier than silver.

Why is platinum less reactive?

This article is on reactivity series of metals. The transition metals (such as iron, copper, zinc, and nickel) are slower to oxidize because they form a passive layer of oxide that protects the interior. Others, like palladium, platinum and gold do not react with the atmosphere at all.

Why is platinum denser than brass?

Platinum is denser than Brass because the particles of Platinum are closely packed while those of Brass. If an object has greater mass and less volume then its density will be more.

Is platinum heavy or light?

Platinum is a very strong and heavy metal. The wearer of a platinum piece will have to decide if they can handle a heavier metal like platinum over a lighter metal like white gold.

Is platinum a flexible metal?

Platinum is a softer and more flexible metal than white gold. Over time, because it is easier to scratch, platinum develops a natural patina (grayish-white dull color) that many people prefer to the polished finish. Platinum is a much denser metal.
