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.

∙ 9y agoEvery form of technetium is radioactive and that makes it unstable. With a Periodic Table number of 43, it is the lowest number that has no stable isotopes.

What is an unstable isotope?
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
An unstable isotope with extra energy in the nucleus?
A radio-isotope.
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
What is the difference between a stable isotope and a unstable isotope?
A stable isotope does not decay and therefore, maintains a constant concentration on Earth. An unstable isotope, also known as a radioactive isotope, decays at a predictable and measurable rate on Earth. An unstable isotope may decay by the ejection of an electron or positron, known as beta decay, or by the ejection of two protons and two neutrons, known as alpha decay.

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.
What is isotope and radio isotope?
Isotopes are atoms of a particular element with different numbers of neutrons. A radio isotope is an isotope that is radioactive because the nucleus is unstable.
Is carbon 13 unstable?
No, it is a natural stable isotope.
Hydrogen has how many unstable isotopes?
Hydrogen has 1 unstable isotope, and 2 stable isotopes.
What best describes a radioisotope?
its nucleus is unstable
Are All isotope unstable?
Not all isotopes are unstable. But now more than 3 000 unstable isotopes are known, artificial or natural.
