What are the uses of francium?
Francium has no uses, having a half life of only 22 minutes. Francium has no known biological role. It is toxic due to its radioactivity. Francium is obtained by the neutron bombardment of radium in a nuclear reactor.
Which among the following is the result the alpha emission of francium-223?
Francium-223 is the element’s longest lived isotope. It has a half-life of 22 minutes. It can emit an alpha-particle (a helium nucleus) to form astatine-219 or a beta-particle to form radium-223.
Where is francium found in the world?
francium (Fr), heaviest chemical element of Group 1 (Ia) in the periodic table, the alkali metal group. It exists only in short-lived radioactive forms. Natural francium cannot be isolated in visible, weighable amounts, for only 24.5 grams (0.86 ounce) occur at any time in the entire crust of Earth.
Why is francium so rare?
Francium is extremely rare. Because of this its chemical and physical properties are not known. It has been studied by radiochemical techniques, which show that its most stable state is the ion Fr+. Francium is the least electronegative of all the known elements.
How much is francium worth?
1. Francium – approximately $1 billion per gram. You might ask how could such an element be so expensive. The cost of this element comes from the fact that its half-life is only 22 minutes.
What happens when you put francium in water?
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 beta emission of francium-223?
Francium-223 is a fifth product of the uranium-235 decay series as a daughter isotope of actinium-227; thorium-227 is the more common daughter. Francium-223 then decays into radium-223 by beta decay (1.149 MeV decay energy), with a minor (0.006%) alpha decay path to astatine-219 (5.4 MeV decay energy).
What happens if you put francium in water?
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.
What is the price of francium?
around $1 billion
If you were to somehow amass a gram of Francium the cost is estimated to be around $1 billion.
What is the cost of 1 gram of francium?
If you were to somehow amass a gram of Francium the cost is estimated to be around $1 billion.
What is the most explosive chemical?
Azidoazide azide
Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.
What is the half-life of francium-223?
22 minutes
Though it is the longest-lived isotope of francium, francium-223 has a half-life of only 22 minutes.
What happens if you throw francium in water?
Has anyone found francium?
As it turns out, francium was one of the last natural elements to be discovered, and is the second rarest after astatine.
What is the most valuable in Earth?
1. Antimatter. Antimatter is by far the most expensive material on Earth. Although only very small amounts have ever been produced, there is currently no way of storing it.
What is the most explosive explosive?
What two chemicals will explode when mixed?
Peroxides (inorganic), when mixed with combustible materials, barium, sodium, and potassium, form explosives that ignite easily. Phosphorus (P), both red and white, forms explosive mixtures with oxidizing agents. White (also called yellow) P should be stored under water, in glass, because it is pyrophoric.
How much is francium worth per gram?
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.
How much does a gram of antimatter cost?
about $62.5 trillion a gram
Right now, antimatter is the most expensive substance on Earth, about $62.5 trillion a gram ($1.75 quadrillion an ounce).
What are the 3 types of explosives?
1. Introduction
- blasting and bulk explosives (explosives used for commercial blasting applications or for their manufacture);
- perforating explosives (intended for use in the oil and gas well industry);
- special-application explosives (high explosives used for other applications, including primary explosives).
What is the most powerful chemical explosive?
What is the best explosive?
One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.
Which country has antimatter?
Scientists from six Indian research bodies are excited over the detection of the heaviest ever antimatter by the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory, USA1.
Where is antimatter found on Earth?
Van Allen belt
The antiprotons were discovered in a particular region of the Van Allen belt called the South Atlantic Anomaly, where the inner ring of the belt dips closest to Earth’s surface.
