No not all isotopes are radioactive, However there certainly are several elements which have no stable isotopes.
these are the man made elements also known as "Not found in nature". such as:
Tc - Technetium (43)
Pm - Promethium (61)
Np - Neptunium (93)
Pu - Plutonium (94)
Am - Americum (95)
Cm - Curium (96)
Bk - Berkelium (97)
Cf - Californium (98)
Es - Einsteinium (99)
Fm - Fermium (100)
No.
No, not all isotopes are radioactive. Only atoms that are unstable (carbon-14, etc.) are radioactive

∙ 15y agoNo not necesserily. because isotopes are of two types
# Ionic # non-ionic Mainly the ionic isotopes are radioactive. Some non-ionic are also radioactive but not all.
Wiki User
∙ 13y agoNo, an isotope just means it's a variation on an element, it has a slightly different number of neutrons in its atomic structure, it doesnt make it radioactive.
Wiki User
∙ 9y agoYes, by definition all radioactive isotopes have unstable nuclei. This causes them to decay in an attempt to reach a stable state.

What is the difference between radioactive and non-radioactive isotope?
Radioactive minerals are unstable and emit radiation at a constant rate. They also have half lives and lose energy overtime. Nonradioactive minerals are stable, and by there own are incapable of emitting energy.
What must occur before a radioactive atoms ceases to undergo further radioactive decay?
A stable, nonradioactive atom must be formed.
If you had a stable element 115 could you then have an isotope of it that would be non-radioactive?
If you had a stable element 115, then by definition there would need to be at least one non-radioactive isotope. Stable elements are those that have at least one nonradioactive isotope. Of course, the other isotopes of the element could all be radioactive.
What happens to all radioactive isotopes?
All radioactive isotopes will disintegrate.
Why nonradioactive substances becomes radioactive when placed near a radium compound?
This phenomenon is not mandatory.
How are isotopes used in carbon dating?
The ratio of carbon-14 (radioactive) to carbon-12 (nonradioactive) is measured.
Why can radioactive isotopes be followed through a chemical reaction?
They emit radiation that can be detected with various radiation measurement tools. Usually the isotopes will be in only one of the products of the chemical reaction, making it radioactive and the others nonradioactive.
Do isotopes exhibit the same chemical atomic properties yes or no?
No, there are differences in chemical properties of different isotopes of the same element. For instance, certain isotopes will be radioactive while other isotopes will be stable and nonradioactive. Also, the different isotopes of hydrogen are significantly different depending on the number of neutrons present.
What is the difference between radioactive and non-radioactive isotope?
Radioactive minerals are unstable and emit radiation at a constant rate. They also have half lives and lose energy overtime. Nonradioactive minerals are stable, and by there own are incapable of emitting energy.
What are isotopes considered radioactive?
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
What must occur before a radioactive atoms ceases to undergo further radioactive decay?
A stable, nonradioactive atom must be formed.
Create a list of element names for the 10 non radioactive gaseous elements?
Hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, xenon, and krypton are all gasses are usually found in nonradioactive isotopes. Hydrogen, chlorine, argon, and krypton have at least traces of naturally occurring radioactive isotopes, however.
If you had a stable element 115 could you then have an isotope of it that would be non-radioactive?
If you had a stable element 115, then by definition there would need to be at least one non-radioactive isotope. Stable elements are those that have at least one nonradioactive isotope. Of course, the other isotopes of the element could all be radioactive.
How are radioactive isotopes different from isotopes?
Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
Does sodium contain radioactive isotopes?
Sodium has no radioactive isotopes.
Does radioactive isotopes have a stable nuclei?
Radioactive isotopes are not stable.
Does plutonium have isotopes that are all radioactive?
All the uranium isotopes are radioactive.
