The two isotopes (or varieties) of the element uranium, U238 and U235 have slightly different weights due to different numbers of neutrons in the nucleus. But, they have the same atomic number (meaning they have the same number of protons in the nucleus and the same number of electrons bound to the nucleus). Because they have the same number of electrons, from a chemical point of view, they are identical: that is, they form the same kinds of bonds with other elements and they cannot be separated by chemical means.
What else can I help you with?
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.
Depleted uranium is chemically thee same as natural uranium but?
Has had most of the uranium-235 (an isotope of uranium)) separated out of it.
Uranium -235 and uranium -238 are different of uranium?
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.
What is uranium 235 when added to natural uranium?
When uranium-235 is added to natural uranium, it increases the overall percentage of uranium-235 in the mixture. This can make the uranium more suitable for use in nuclear reactors or weapons, as uranium-235 is more fissile (more easily split by neutrons) than uranium-238.
Which two notations represent different isotopes of the same elements?
Example with the istope 235 of uranium: - 235 92U (recommended) or - U-235

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.
What is the percentage of uranium-235?
Uranium-235 is an isotope of uranium making up about 0.72% of natural uranium.
What percentage of mined uranium is 235?
Approx. 0,7 % uranium 235 in natural uranium.
How many protons in uranium-235 atomic number 92 after undergoes fission?
After undergoing fission, the number of protons in the uranium-235 nucleus will remain the same. Uranium-235 has 92 protons, and fission does not change the number of protons in the nucleus.
What is uranium 235 when added to natural uranium?
When uranium-235 is added to natural uranium, it increases the overall percentage of uranium-235 in the mixture. This can make the uranium more suitable for use in nuclear reactors or weapons, as uranium-235 is more fissile (more easily split by neutrons) than uranium-238.
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.
Which two notations represent different isotopes of the same elements?
Example with the istope 235 of uranium: - 235 92U (recommended) or - U-235
What is the same between uranium 235 and uranium 238?
The both have 92 protons in their nucleus and the same chemical properties. Their NUCLEAR properties are different.
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.
An isotope of uranium using nuclide notation?
The chemical symbol of uranium is U.
