Yes. Stable elements are 83 elements. all elements above that of atomic number 83 (Bismuth) are radioactive. Radioactive isotopes are of the order of 1500 radioactive isotope.

What elements that emit atomic particles are called?
radioactive elements
When radioactive isotopes break down into other elements the process is called?
radioactive decay
All synthetic elements are?
radioactive
What are the things with radiation?
radioactive elements
List of radioactive elements?
Elements that decay (give off protons and neutrons) to form other elements. *It's not elements as such that are stable or unstable, but rather isotopes. Even elements of small atomic number have unstable isotopes that undergo radioactive decay, for example carbon-14. Elements with higher atomic numbers than Lead (82) are naturally radioactive in all isotopes. Bismuth (83) has an extremely long half-life, but the time generally becomes shorter (the decay more rapid) as the size of the nucleus gets progressively larger for heavier radioactive elements.
Synthetic elements comprise a majority of which of the following groups?
Artifficial radioactive elements are situated in: - period 7 - actinoids (actinides) family
What does the radioactive elements comprise a majority or the periodic table?
All elements after Uranium (U) are radioactive. Much of that is due to the fact that they are so large and unstable, that decay causes more stability. This description ignores complex quantum mechanics such as the weak force, one of the four fundamental forces, driving radioactive decay.
Which group contains only radioactive elements?
The actinoids (formerly actinides) are all unstable metallic elements. The period 7 elements with atomic numbers from 89 (actinium, for which the group is named) through 103 comprise these elements. A link can be found below.
What element is radioactive and explosive?
There are at least 50 different elements produced in a nuclear explosion, most are fission products in 2 peaks, some are formed by neutron capture and beta decay. The majority of these are radioactive isotopes of the elements.
Do trace elements have to be radioactive?
No, trace elements are not necessarily radioactive. A link to a list of elements that have no natural radioactive isotopes is at a related question, below.
What made up all radioactive elements?
After disintegration all radioactive elements are transformed in other elements.
What elements comprise silver?
Silver is an element, there are no other elements in it.
Are all transition elements are radioactive?
Not all of the transition elements are radioactive. Many of them are, and some of them have common radioactive isotopes, but some of them have no naturally occurring radioactive isotopes. Please note that all elements have synthetic radioactive isotopes, at least.
The pressure and heat that produces magma are caused in part by?
Radioactive elements
What families have no radioactive elements?
Radioactive elements exist in all groups of the periodic table.
What element family have no radioactive elements?
Radioactive elements exist in all groups of the periodic table.
What elements are radioactive?
Answerelements with a nonstable isotope or at least one naturally occurring isotope that is radioactive. AnswerAll elements have radioactive isotopes.There are a lot of radioactive elements: Technetium, Promethium, Polonium, Astatine, Radon, Francium...Here is the whole list: http://periodictable.com/Elements/Radioactive
