If we are talking about the nuclear bombs used in ww2, 1 plutonium bomb and 1 uranium bomb.
This element is phosphorous.
Both Uranium-235 and Plutonium-239 were used to fuel the WW2 fission bombs. Both are still used, although there is a preference for Plutonium now.
No, Francium is not used in bombs. Due to its high radioactivity and scarcity in nature, Francium is not a practical element to use in weapon applications.
Uranium is the element commonly used to generate electricity in nuclear power plants and as the primary material for nuclear bombs. It undergoes nuclear reactions such as fission to release large amounts of energy.
magnesium
It depends which type it is. It can be Uranium or Plutonium
Uranium is enriched in the isotope uranium-235, producing uranium-238 as waste.
Apparently it was plutonium which I think is element 295.Plutonium is element 94.Plutonium was used in the Gadget at Trinity.Uranium was used in the first bomb dropped on Japan the Little Boy at Hiroshima.Plutonium was used in the second bomb dropped on Japan the Fatman at Nagasaki.
Uranium is a natural chemical element, metal, solid, toxic, radioactive, reactive, very dense, used as fuel in nuclear reactors, used in nuclear bombs, used in alloys for tankks armors, etc.
Einsteinium is not used in bombs.
The element commonly used in flares, flash bulbs, and incendiary bombs is magnesium. When ignited, magnesium burns very brightly, making it ideal for these applications.
It was used in olden day bombs but not today!
