Any given element has a specific number of protons, but the number of neutrons varies; an isotope has a specified number of nucleons (protons plus neutrons). Hydrogen 1 has no neutrons, hydrogen 2 (also known as deuterium) has one neutron, hydrogen 3 (or tritium) has two neutrons.

Uranium -235 and uranium -238 are different of uranium?
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
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.
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.
What are uranium atoms?
Uranium has three natural isotopes and many artificial isotopes. Uranium 238 has 92 protons and electrons and also 146 neutrons.
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.
Uranium -235 and uranium -238 are different of uranium?
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
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 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.
Who discovered the radioisotopes of uranium?
Because uranium has approx. 26 isotopes it is difficult to list here the history of these discoveries.I recommend to read the link below.
Is the isotope of uranium you found in a stable r radioactive?

Is uranium naturally occurring or is it syntherically made?
Uranium has three natural isotopes: 234, 235 and 238; also uranium has ca. 25 artificial isotopes.
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.
Why uranium is most common in isotopes?
The most common isotope of uranium is uranium-238.
What is a Toxic metallic element decay product of uranium?
The end products of uranium isotopes decay chain are the isotopes of lead.
Does plutonium have isotopes that are all radioactive?
All the uranium isotopes are radioactive.
