Fast Facts: The Most Expensive Natural Elements

The most expensive natural element is francium, but it decays so quickly it can't be collected to be sold. If you could buy it, you'd pay billions of dollars for 100 grams. The most expensive natural element that is stable enough to purchase is lutetium.

How much is francium cost?

Francium – approximately $1 billion per gram

The cost of this element comes from the fact that its half-life is only 22 minutes. The billion per gram is completely theoretical, since one gram of francium has never even been observed.

Where can I find francium?

Francium is obtained by the neutron bombardment of radium in a nuclear reactor. It can also be made by bombarding thorium with protons.

Is francium hard to get?

Outside the laboratory, francium is extremely rare, with trace amounts found in uranium and thorium ores, where the isotope francium-223 continually forms and decays.

Is francium very rare?

As it turns out, francium was one of the last natural elements to be discovered, and is the second rarest after astatine. Estimates of the abundance of francium suggest that there is only about 30 g in the whole of the Earth's crust.

The most expensive element on Earth: $1 billion per gram!

Has anyone found francium?

Francium is the last naturally occurring element to be discovered. After several erroneous claims, it was finally discovered in 1939 by the French physicist, Marguerite Perey, who began her scientific career as a student of two-time Nobel Laureate, Marie Curie.

What can francium be used for?

Francium has been used in the field of research, chemistry and also in the atomic structure. It is used for diagnostics for curing cancers. It is also used in many spectroscopic experiments. Francium is a highly radioactive metal, and since it exhibits a short half-life, it does not have more impact on the environment.

How explosive is francium?

The piece of francium would blow apart, while the reaction with water would produce hydrogen gas, francium hydroxide, and a lot of heat. The entire area would be contaminated with radioactive material.

What is the rarest element in the world?

Astatine is the rarest element on Earth; only approximately 25 grams occur naturally on the planet at any given time. Its existence was predicted in the 1800s, but was finally discovered about 70 years later. Decades after its discovery, very little is known about astatine.

What happens if you touch francium?

Francium is a radioactive metal, also known as an alkali metal because it has one valence electron. And if you didn't know, Alkali Metals are super reactive to water. If Francium were to touch water, it would cause a huge explosion. The explosion would be so dangerous and would be fatal.

Which element is most costly?

As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume.

Is francium the rarest element?

Francium is the second rarest element in the Earth's crust, next to astatine. Less than thirty grams of francium exists on Earth at any given time. Francium is the least electronegative of all the elements, therefore it should be the most chemically reactive alkali metal.

How do I sell francium?

The most expensive natural element is francium, but it decays so quickly it can't be collected to be sold. If you could buy it, you'd pay billions of dollars for 100 grams.

How much does 1 kg of plutonium cost?

Since the energy per fission from plutonium-239 and uranium-235 is about the same, the theoretical fuel value of fissile plutonium can be put at $5,600 per kilogram.

What is the most precious metal?

This list of the top precious metals in jewelry, however, identifies each of the most valuable metals in the platinum group, individually.

1. Rhodium: Top Most Valuable Metal. Rhodium is the most valuable metal and exists within the platinum group of metals. ...
2. Palladium: 2nd Most Valuable Metal. ...
3. Gold: 3rd Most Valuable Metal.

What is the rarest thing in the galaxy?

Astronomers recently mapped the rarest type of galaxy ever found: an elliptical galaxy sporting rings of young stars. Most galaxies, including our own Milky Way, are spiral or elliptical. But this recently mapped galaxy, called PGC 1000714, is unique.

What is the rarest material in the universe?

Element Astatine.

The rarest naturally occurring element in the universe. Discovered in 1940.

What happens when you mix fluorine and francium?

Because francium is known to be a real alkali metal, its reaction with fluorine should lead to the formation of FrF.

What element blows up with water?

For decades, science enthusiasts have delighted at the famously energetic way sodium and potassium explode on contact with water.

What happens if you drop liquid cesium?

But toss it in water, or just leave it exposed to the ambient air, and it will self-ignite to send up purplish-pink chemical flames. Even if the stuff is cooled to minus 177 degrees Fahrenheit, dropping it in water will cause an explosive reaction with the oxygen in the liquid.

What does francium taste like?

Francium is a very unstable metal. Francium has a silvery, and gray color to it. No one has tasted francium because francium is very rare and it would kill you.

What state is francium at 30 degrees?

Francium is a chemical element with symbol Fr and atomic number 87. Classified as an alkali metal, Francium is a solid at room temperature.

Why is francium not used in schools?

Because francium is so rare, and lasts for such a short amount of time, there aren't any uses for it. Nothing can be manufactured with it; it's only used by scientists who are studying the properties of elements in the laboratory.
