Uranium

Uranium is a heavy element with the atomic number 92 and the symbol U. In 1789 it was discovered in the mineral pitchblende by Martin Heinrich Klaproth , who named it after the planet Uranus

Uranium

Why is uranium radioactive?

Positives repel each other. In an atom, the nucleas is full repelling protons with their positive charge. It is the nuclear force that holds them together in the nucleus. A Helium atom has only 2 protons which makes it more stable.

Uranium on the other hand, has 92 protons all squashed together. This makes it very unstable which allows it to undergo gamma radiation.

That is why Uranium is radioactive.
Unstable atoms as uranium are radioactive; the stability depends on the ratio between protons and neutrons.

What is the periodic symbol origin for Uranium?

Uranium, Neptunium and Plutonium follow each other - elements 92,93,94. They are named after the outer planets though Pluto is no longer classed as a planet. U was chosen as there was no conflict with other elements names beginning with U.

Can you reuse Uranium?

Uranium can be reused as nuclear fuel or for other applications.

For the most part, Uranium is most useful in it's U-235 form, and also for being converted into P-239 (Plutonium). As natural Uranium is over 99% U-238, various processing methods are used to increase the percentage of U-235 to a level where it is usable in reactors. Very small amounts of U-238 or U-233 are also useful in things like RTGs (Radio-Thermal Generators).

Essentially, "used" Uranium can always be reprocessed, extracting the contaminant elements, and then enriching it back up with U-235. Or, it can use bombarded with a neutron source to produce Plutonium.

One of the US's big problems with its nuclear reactor waste fuel is that the US currently refuses to consider recycling this fuel. Recycling "spent" reactor fuel can result in a 90% total reduction in final waste - that is, we can likely recycle a given fuel rod for reuse over 10 times. The fact that this is NOT being done is a huge idiocy within our use of nuclear power - most other countries recycle their fuel, so it's a well-known and understood process.

How big is Romania's uranium production?

The uranium production of Romania is now modest: probably not more than 200 t/year (as metal). The production of nuclear fuel for the Cernavoda Nuclear Power Plant is also approx. 200 t/year as sintered uranium dioxide.

Is uranium reusable or not?

Uranium can be "recharged" from isotope 238 to isotope 235 but it is an expensive process and it is more economical to mine more since Uranium is about as common as Tin in the earth's crust. Depleted Uranium (238) is an extremely dense metal and has found its way into a few (mostly military) applications such as certain modern tank armor and special armor piercing bullets. This is the only practical way of "reusing" Uranium.

Uranium

What is the Weight of 1 cubic meter of uranium?

density = 19.05 grams per cubic centimetre

cubic centimetres in a cubic metre = 10^6 = 1,000,000

19.05 x 1,000,000 = 19.05 million grams

19.05 million grams = 19,050 kilograms = 19.05 metric tons = Mass

19,050 kilograms x 9.81 = 186,880.5 Newtons = Weight

Where do 2 electrons of uranium go in alpha decay of uranium-238?

Electrons do not go anywhere. Alpha decay involves the loss of two protons and two neutrons from the nucleus (it is beta decay which involves the loss of an electron, and other particle changes).
