Uranium-235 and uranium-238 are natural, radioactive isotopes of uranium; they have 92 protons and electrons but the number of neutrons is different:
- for 235U: 143
- for 238U: 146
The main difference between uranium-235 and uranium-238 is their atomic masses. Uranium-235 has 235 atomic mass units (AMU) while uranium-238 has 238 AMU. This difference in mass is due to the number of neutrons in the nucleus of each isotope.
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.
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.
The full atomic symbols for uranium are: Uranium-235: ^235U Uranium-238: ^238U
The main difference is in the number of neutrons present in the nucleus. Uranium-235 has 143 neutrons, while uranium-238 has 146 neutrons. This leads to differences in their relative abundance and stability.

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.
Uranium-235 is more explosive than uranium-238. This is because uranium-235 is fissile, meaning it can sustain a chain reaction of nuclear fission, which releases a large amount of energy. Uranium-238 is not fissile and requires a neutron source to undergo fission.
The main difference is in the number of neutrons present in the nucleus. Uranium-235 has 143 neutrons, while uranium-238 has 146 neutrons. This leads to differences in their relative abundance and stability.
Uranium-235 is found in nature at about 0.7% concentration to uranium-238.
