Uranium is a chemical element and doesn't contain other elements,
As all chemical elements uranium is formed from protons, neutrons and electrons.
Uranium and Plutonium
Its one of only 2 elements that have fissile isotopes, the other is plutonium which must be manufactured from uranium in reactors.
Yes, chemical compounds are made up of elements combined together.
Plutonium has the same composition as uranium, except for the fact that it contains one more neutron and one more proton. Actually Plutonium-239 has 2 more protons and 2 more neutrons than Uranium-235.
yes
So far as I know, there are no "2 what and 2 what"s that make up uranium. Uranium has 92 protons in its nucleus and 92 orbital electrons. The number of neutrons in the nucleus depends on what isotope you are interested in.
She discovered radioactivity and 2 elements, polonium and radium.
I say there are 92. At school, we were taught that there are 92 naturally occurring chemical elements on Earth. They are all the elements from hydrogen to uranium. However it's a bit more complicated than that. Here's some more detail: There are 2 elements of the first 92 that are so unstable they are not found in nature. Actually minute traces of these have now been detected, I believe. There are 2 elements beyond uranium that do occur naturally as the product of the radioactive decay of Uranium. So, the final total is probably 92. However, it may be anything from 90 to 94, depending on what you include.
In World War 2 the Nuclear bombs were Uranium and Plutonium. Nowadays they use Hydrogen.
The oxygen to uranium ratio is exactly 2 for the stoichiometric uranium dioxide (UO2). 2 oxygen atoms/1 uranium atom = 2
no, these are the only elements with isotopes both unstable enough to support a nuclear chain reaction yet stable enough to not spontaneously fission too much causing a fizzle. these isotopes are uranium-235 (natural), plutonium-239 (bred from uranium-238), uranium-233 (bred from thorium-232).however once you have a fission bomb it is possible to add the following elements to make far more powerful fusion bombs: hydrogen and lithium. the necessary isotopes are hydrogen-2 (aka deuterium, natural), hydrogen-3 (aka tritium, bred from lithium-6 or lithium-7), lithium-6 (natural), lithium-7 (natural).
