Isotopes are atoms of the same element that have the same number of protons, but different numbers of neutrons, and therefore different masses. Unstable isotopes are radioactive and undergo radioactive decay of their nuclei, while stable isotopes do not undergo radioactive decay.
An element can be radioactive regardless of its number of protons. Radioactivity depends on the specific isotopes of an element, which can have different numbers of neutrons. Elements with unstable isotopes that undergo radioactive decay typically have too few or too many neutrons compared to the number of protons.
Isotopes of elements are atoms with the same number of protons but different numbers of neutrons. This causes isotopes of the same element to have different atomic masses. Isotopes can be stable or unstable, with unstable isotopes undergoing radioactive decay.
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.
All radioactive isotopes will disintegrate.
The ratio neutrons/protons in radioactive isotopes is the cause of their innstability.

A radioactive element with several isotopes that always has 94 protons within its nucleus.

Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
Radioactive isotopes are not stable.
Sodium has no radioactive isotopes.

All the uranium isotopes are radioactive.
