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.

JudyU-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.

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.
Are uranium 235 and uranium 238 said to be radioactive molecules since they have the same number of protons but different numbers of neutrons?
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.
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 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.
Is the isotope of uranium you found in a stable r radioactive?
All the isotopes of uranium are unstable.Natural isotopes of uranium are: 234, 235 and 238.
