Why is a sample of uranium compound found to be losing mass gradually?
The loss of mass in a sample of uranium compound could be due to radioactive decay, where uranium isotopes (e.g., uranium-238) are converting into other elements and emitting particles in the process. This decay leads to the creation of daughter products and a decrease in the overall mass of the sample over time.
What does 238 represent in uranium?
238 represents the most common isotope of uranium, uranium-238. It is a naturally occurring isotope found in uranium ores and makes up over 99% of natural uranium. It is not fissile, but can be converted into fissile plutonium-239 in nuclear reactors.
What is the halflife of Uranium-239?
The half-life of uranium-239 is 23.45 minutes.
What are the similarities and differences between the isotopes uranium 235 and uranium 238?
Similarities: Both uranium-235 and uranium-238 are isotopes of uranium, meaning they have the same number of protons but different numbers of neutrons. They are both radioactive and can undergo nuclear fission. Differences: Uranium-235 is the primary isotope used for nuclear fuel and weapons due to its higher susceptibility to fission compared to uranium-238. Uranium-238 is more abundant in nature, constituting over 99% of natural uranium, while uranium-235 is less common.
What are the similarities and differences between the isotopes uranium-235 and uranium-238?
Uranium-235 and uranium-238 are the isotopes of the same element - uranium, a natural radioactive chemical element; the atomic number is the same - 92. Also the electronic structure, the number of protons, etc. Differences: atomic mass, number of neutrons, U-235 is fissile with thermal neutrons but U-238 is only fertile, halflife, type of disintegration types and energy of emitted radiations, etc.

Has the amount of uranium in Earth increased over geologic time Has the amount of lead in Earth increased?
The amount of uranium on Earth has remained relatively constant over geologic time, as uranium is a naturally occurring element that is not created or destroyed in significant amounts. On the other hand, the amount of lead on Earth has increased over time due to the radioactive decay of uranium and other elements that eventually form lead isotopes as byproducts.
