Only the end product of the decay chain of uranium, a non radioactive isotope of lead.
The end products of uranium isotopes decay chain are the isotopes of lead.
Yes, that's correct. The uranium decay chain ends with the stable element lead-206. As uranium-238 undergoes alpha and beta decay, it transforms through various radioactive isotopes before reaching lead-206, which is stable and not subject to further radioactive decay.
The air pollution with uranium is generally not important (excepting the area of mines); but the radioactive gas radon, a product of the radioactive decay chain of uranium is very dangerous and responsible for some lung cancers.
The final product of the decay chain is the stable isotope 206Pb.
Mainly because only about 0.7% of uranium is the isotope uranium-235, which is easily fissionable. It is believed that in Earth's remote past, there were such chain reactions - natural reactors - at a time when the percentage of U-235 was higher.
Uranium is a product of mining industry.
Uranium 238 is a natural isotope of uranium, non-fissionable with thermal neutrons, with an atomic mass of 238,050 788 247 ± 0,000 002 044 u.a. and a half life of 4,468 x 109 years, atomic number 92. Natural uranium contain 99.2745 % U 238 (atomic); the desintegration of U 238 is alpha type.
Uranium 235
Uranium is a radioactive metal, member of the actinoids family.
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!
Radium is a decay product of uranium.
