A lot of the natural occurring isotopes are stable, such as those of smaller elements. The bigger an atom is, the more unstable its isotopes may be (not an absolute rule, though).
It is harder to keep the many nuclear parts (protons and neutrons) together if they are so numerous as in heavy elements.
What else can I help you with?
What is an unstable isotope?
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
When an isotope is blank it is radioactive?
When an isotope is unstable, it is said to be radioactive.
When a unstable isotope decays the daughter isotope that result is always a stable isotope true or false?
False. When an unstable isotope decays, the resulting daughter isotope may or may not be stable. Some daughter isotopes are stable, while others may still be radioactive and undergo further decay.
Are All isotope unstable?
Not all isotopes are unstable. But now more than 3 000 unstable isotopes are known, artificial or natural.
What is An unstable isotope is called what?
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.

What is another term for an atom that is unstable?
isotope
What do isotope and half life have in common?
Each (unstable) isotope has a distinctive half-life.
Hydrogen has how many unstable isotopes?
Hydrogen has 1 unstable isotope, and 2 stable isotopes.
When a unstable isotope decays the daughter isotope that result is always a stable isotope true or false?
False. When an unstable isotope decays, the resulting daughter isotope may or may not be stable. Some daughter isotopes are stable, while others may still be radioactive and undergo further decay.
What best describes a radioisotope?
its nucleus is unstable

What do you call an element with unstable nucleus?
Radioactive isotope, or radioisotope.
What is an unstable atom that emits energy called?
This is a radioactive isotope.
