Stable isotopes are isotopes that do not undergo radioactive decay and have constant Atomic Mass. Unstable isotopes, also known as radioactive isotopes, decay over time by emitting radiation.
No. They are not. They undergo nuclear decay at a specific rate for each different isotope.
unstable isotopes have live time measured in "half lives long", stable isotopes don't have it

Does americium has stable isotopes?
All the isotopes of americium are radioactive and unstable.
Which element in group 16 has unstable isotopes?
Polonium is the element in group 16 that has unstable isotopes. It is a radioactive element with no stable isotopes.
Is selenium stable or unstable?
Selenium is generally considered stable in its elemental form. However, some of its isotopes are unstable and undergo radioactive decay.
Are daughter isotopes always stable?
No. Often a decay product is itself unstable and will decay into something else until a stable isotope is reached. This is called a decay chain. For example, Uranium-238 will decay 15 times through various isotopes until it becomes lead-206 which is stable
How many stable isotopes are in the element californium?
There are two stable isotopes of californium: californium-249 and californium-251.
Hydrogen has how many unstable isotopes?
Hydrogen has 1 unstable isotope, and 2 stable isotopes.
Does americium has stable isotopes?
All the isotopes of americium are radioactive and unstable.
Is Xenon stabel or unstable?
It has mostly stable isotopes.
Is this a stable element Carbon atomic number 6?
Yes, carbon (atomic number 6) is a stable element with both stable and unstable isotopes. The most common stable isotope of carbon is carbon-12, which makes up about 98.9% of naturally occurring carbon.
Is O radioactive?
If you mean oxygen: like most elements, it has both stable isotopes, and unstable (i.e., radioactive) isotopes. 16O, 17O and 18O are stable; the unstable (radioactive) isotopes include 15O and 14O.
Which element in group 16 has unstable isotopes?
Polonium is the element in group 16 that has unstable isotopes. It is a radioactive element with no stable isotopes.
Which transition metals are radioactive or unstable?
Technetium has no stable isotopes.

Is nobelium a stable element?
All the isotopes of nobelium are radioactive and unstable.
Is the element hydrogen stable?
The isotopes protium (H-1) and deuterium (H-2) are stable; tritium (H-3) and artificial isotopes are unstable.
