No. All Uranium isotopes are called Uranium because they have 92 protons. The different isotopes (233, 235, 238, etc) all have 92 protons but have different numbers of neutrons in the nucleus. The chemical characteristics of an atom are determined by the number of protons in the nucleus which controls the number of electrons it takes to balance the atom and thus the chemical valence of the atom.
When you get down to it, that is the reason why enrichment of Uranium is such a difficult task since there is only a three neutron difference in weight between fissionable U235 and non-fissionable U238 and no difference in chemical properties.

∙ 13y agoU-235 has a few less neutrons that U-238. But most significantly different are their nuclear fallout times.
It takes U-235 roughly 700 million years to decay, but it takes about 4 billion years for U-238 to decay.
So they differ in nuclear properties but not chemical properties.

∙ 14y agoYes, of course, because the number of neutrons is different.

Uranium -235 and uranium -238 are different of uranium?
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
What are isotopes and how do you label them?
Isotopes are atoms of the same element but with a different number of neutrons.Example for the isotope 228 of uranium:- uranium-228- U-228-- 22892U
What isotope uranium is radioactive?
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.
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.
What isotopes accumulate in old uranium-bearing rock?
Ultimately lead, as it is the only element in the uranium decay chains with isotopes that are stable. Specifically the isotopes 206, 207, and 208; each of which is the end of a different decay chain.

Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
Uranium-235 and uranium-238 are different?
Uranium-235 and uranium-238 are different isotopes of the element uranium. They have different mass numbers due to different numbers of neutrons.
Is Uranium Chemically Active?
No uranium is not chemically active
Does isotopes of uranium have different number of electrons?
No, only the number of neutrons is different.
What are isotopes and how do you label them?
Isotopes are atoms of the same element but with a different number of neutrons.Example for the isotope 228 of uranium:- uranium-228- U-228-- 22892U
Are unstable isotopes chemically inert?
Unstable isotopes can be chemically reactive.
How many isotopes uranium has?
Uranium has 3 natural isotopes (234, 235, 238) and 26 artificial isotopes.All the isotopes of uranium are radioactive.

What are the same between uranium and plutonium?
Both are chemical elements, solid, metals, radioactive, having fissile isotopes, chemically reactive, toxic etc.
Why does both isotopes of phosphorus have identical chemical properties?
All isotopes of a substance are chemically the same. It is their physical properties which are different.
