What is the average atomic mass of uranium that has three common isotopes if the abundance of 234U is 0.01the abundance of 235U is 0.71 and the abundace of 238U is 99.28.?

Due to the fact that more than 99 % of all natural uranium is U-238, the average Atomic Mass is 238. The isotope U-234 is also a natural isotope (0.0058%); the uranium average mass is 238.02891 ± 0.00003 (IUPAC, Atomic weights 2005).

What is the decay element of uranium?
It is not yet discovered since all of the uranium isotopes are having half life for several millions of years. We would be able to find it after atleast 700 millions of years.
Why is lead mixed in with all deposits of uranium?
Because the stable isotopes of lead are the end products of the decay chain of uranium natural radioactive isotopes. or because lead is the product of decayed uranium... that should be a good enough answer for your chem teacher you cheater!
Compared to the mass of a uranium nucleus before splitting the pieces it splits into have?
The masses of fission products are of course smaller than the masses of uranium isotopes.
How many protons are in the isotope 235 92 U of Uranium?
235 (mass number) - 92 (number of protons) = 143 (number of neutrons)
Why is urainium a non renewable fuel?
Uranium is a non-renewable fuel. The earth has a limited supply of this mineral. Uranium ore is mined, then refined for use in power plants. It can not be put back. The earth is not creating more uranium. As with any non-renewable fuel, we should be concern about the supply. If additional quantities are discovered, the uranium that is known to us, can increase. See related link on abundance of uranium and other minerals.
Uranium -235 and uranium -238 are different of uranium?
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
What are the fertile isotopes of Uranium?
There are many isotopes for uranium, the most abundant of them in nature are:Uranium- 234, having 142 neutron and 92 protonUranium- 235, having 143 neutron and 92 protonUranium- 238, having 146 neutron and 92 protonThe abundance of these three isotopes in natural uranium is:Uranium-234: 0.006 %Uranium-235: 0.720 %Uranium-238: 99.274 %
How many isotopes uranium has?
Uranium has 3 natural isotopes (234, 235, 238) and 26 artificial isotopes.All the isotopes of uranium are radioactive.
What isotope uranium is radioactive?
Yes.......most likely. I can't think of anything to do with Uranium, that isn't radioactive! -------- Uranium natural isotopes are not so radioactive compared with other isotopes; but all the isotopes of uranium are radioactive.
Is the isotope of uranium you found in a stable r radioactive?
All the isotopes of uranium are unstable.Natural isotopes of uranium are: 234, 235 and 238.
What are uranium atoms?
Uranium has three natural isotopes and many artificial isotopes. Uranium 238 has 92 protons and electrons and also 146 neutrons.
Does uranium not have a stable isotope?
Uranium hasn't stable isotopes.
Is uranium naturally occurring or is it syntherically made?
Uranium has three natural isotopes: 234, 235 and 238; also uranium has ca. 25 artificial isotopes.
Is uranium the element rare?
abundance of uranium in the earth crust; 2,5-3 ppm (mg/kg) abundance of uranium in the sea water: ca. 3 ppb (?g/kg)
Are uranium 235 and uranium 238 said to be radioactive molecules since they have the same number of protons but different numbers of neutrons?
No, Uranium-235 and uranium-238 are radioactive, natural isotopes (not molecules, but atoms) of the one and the same element: uranium.Both with 92 protons and 235-92 = 143 neutrons in U-235 but 146 neutrons in U-238.
What are the different isotopes of uranium?
Uranium metal has three allotropic forms:α (orthorhombic) stable up to 660 °Cβ (tetragonal) stable from 660 °C to 760 °Cγ (body-centered cubic) from 760 °C to melting point-this is the most malleable and ductile state.And if you think to the isotopes, uranium has 3 natural isotopes: 234U, 235U,238U and ca. 24 artificial isotopes, all radioactive.And if you think to enrichment (concentration of 235U) uranium may be: depleted, natural, low enriched, highly enriched.
Why uranium is most common in isotopes?
The most common isotope of uranium is uranium-238.
