You are orobably thinking of the small cylinders which make up the fuel rods. These are 10mm diameter and about 10mm long, and are packed end to end inside the zircaloy sheath to make a fuel rod. The material is uranium dioxide with the uranium enriched to about 5% U-235.
Uranium pellets are usually shaped in a cylindrical form with dishing and with sloped edges then roasted in an incinerator,
You don't say how big your pellet is. 1 kg of uranium 235 will give as much energy as 1500 tonnes of coal
# I'm not clear what size pellet you mean. However for Uranium235 (the fissile isotope), if it is fully used up, 1 kg will give as much energy as 1500 tonnes of coal, ie 1,500,000 kg of coal, so that is the ratio, 1,500,000 to 1. Of course uranium as loaded into the reactor is actually about 4 percent U235, the rest U238 which is not fissile, so the U235 is 1/25 of the total weight of uranium, and if you mean the total uranium weight you therefore have to reduce this ratio by 25, and get 60,000 to 1.
Some examples of uranium compounds are: uranyl nitrate, uranium dioxide, uranium hexafluoride, uranium tetrachloride, triuraniumoctaoxide, uranyl acetate, uranium iodide, uranium nitride, uranium, sulfide, uranium carbide, uranyl sulfate, etc.
Yes, uranium and all the compounds of uranium are toxic and radioactive.Yes, uranium is toxic and radioactive.
Uranium is a metal, uranium oxide is a compound of uranium and oxygen, UO2
None. A pellet of uranium contains uranium, not coal.

7 g 235U is approx. equivalent to 20 t coal (for the complete fission of the uranium).
Depends on the size of your pellet. 1 kg of Uranium235 is equivalent to 1500 tonnes of coal.
Not necessary for natural uranium; the most energetic gamma radiation of natural uranium has an energy of only ca. 183 keV uranium; uranium is not so dangerous as a radioactive element. Uranium is more toxic - ingested or inhaled.
7 g 235U is approx. equivalent to 20 t coal (for the complete fission of the uranium).
About 1500 tons of coal
There are many types of uranium pellets depending on the nuclear reactor type and the used uranium enrichment (or uranium-235 content). It may be more illustrative to say that: 1 gram of uranium-235 when undergoes fission in a nuclear reactor gives energy roughly equivalent to burning 3 tonnes of coal or 2 tonnes of oil.

One uranium fuel pellet about the size of a thimble can generate the same amount of energy as roughly one ton of coal.
