Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.
And of course the atomic masses are different.
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.
Uranium isotopes
Uranium-238 and uranium-234 are not "elements", but they are natural isotopes of the chemical element uranium. The atoms are neutral.
Uranium is a metallic element and is not classified as an acid or a base. It is a radioactive element that can be found in nature as uranium-238 and uranium-235 isotopes.
There are 92 protons in the nucleus of an atom of 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.
Differences between uranium isotopes: atomic mass, half life, type of decay, energy and types of emitted radiations, specific activity, number of neutrons, artificial or natural isotope, mode of preparation, etc.
Uranium isotopes have the same chemical properties due to their identical electron configurations, making it challenging to separate them using traditional chemical methods. The separation is usually achieved through physical methods, such as centrifugation or gas diffusion, which rely on the small mass differences between the isotopes.
Uranium-235 and uranium-238 are two isotopes of uranium with different numbers of neutrons. Uranium-235 is used in nuclear reactors and weapons due to its ability to sustain a nuclear chain reaction, while uranium-238 is mainly used in depleted uranium ammunition and as a source of fuel for nuclear reactors. The main difference between the two isotopes is their nuclear properties and applications.
Differences between uranium isotopes: natural isotopes (U-234, U-235, U-238) and the artificial isotopes; differences in atomic mass; differences in the number of neutrons; differences of the half life; differences in the emitted radiations (type, energy, percentage); differences in the decay chain; differences in the technological importance; etc.
Uranium has 3 natural isotopes (234, 235, 238) and 26 artificial isotopes.All the isotopes of uranium are radioactive.
Absolutely correctly speaking the density of different isotopes are not identical; but the differences are very small, especially for heavy isotopes.
Uranium isotopes
Uranium-235 and uranium-238 are isotopes of uranium, meaning they have the same number of protons but different numbers of neutrons. Uranium-235 is used in nuclear reactors and weapons due to its ability to sustain a nuclear chain reaction, while uranium-238 is more abundant in nature but less useful for these purposes.
All the isotopes of uranium are unstable.Natural isotopes of uranium are: 234, 235 and 238.
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.
Uranium-235 and uranium-238 are not considered molecules, they are isotopes of uranium. Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons. Both uranium-235 and uranium-238 are radioactive isotopes, meaning they spontaneously decay and emit radiation.
