It is the second rarest natural element, following astatine. Possibly, though francium is too rare and its half-life too short for it to have any practical uses, there may have been a Francium Bomb tested in the Pacific. No comments: Post a comment. A fresh francium surface would soon tarnish because of reaction with oxygen and moisture from the air. The test would be the first of many by France. Full Screen and Clear; Online Alarm Clock - An Online Alarm Clock! H20 (water) is forced into the chamber holding the chunk of francium, creating a reaction, which in turn causes a grand explosion.

Francium Properties. Share to Twitter Share to Facebook Share to Pinterest. France conducted its first nuclear bomb test at Reganne, Algeria, in the Sahara desert. Nuclear or Hydrogen bombs are just cheaper and easier to make than a Francium bomb. I dont think it is appropriate to do a flame test on francium.It is very rare.If I had to guess I would say it gives a blue colour.It is not an element which the question should be asked. Calling, always calling, not understanding, but calling still. Francium being the most unstable metal of the first 105 is said to be the most ignoble metal and has the largest atomic diameter. Pakistan celebrates 21st anniversary of being 1st Islamic nuclear power It has a half-life of 22 minutes. It used to be known as actinium K and eka caesium and has a metallic color.

The Trinity test on 16 July 1945, near Socorro, New Mexico, was the first-ever test of a nuclear weapon (yield of around 20 kilotons). The least stable isotope, Fr-215, has a half-life that—in its metastable isomer state—is only 3.5 nanoseconds. NUKEMAP is a mapping mash-up that calculates the effects of the detonation of a nuclear bomb. Francium is very scarce and expensive. Francium’s isotopes, with mass numbers ranging from 200 to 232, most commonly undergo alpha- or beta-decay. I suppose it might have some use where you need the bomb to be as small as possible, normally it would be more practical to just use a larger bomb made of some more conventional explosive. Views 7700. The one you described causes as much damage as a large conventional bomb. Number of protons in Francium is 87.
