No. All elements with atomic number greater than 83 are radioactive, including some metals such as polonium, uranium, etc. But there are radioactive isotopes of most metals on the periodic table but are very rare and sometimes must be produced in reactor or particle accelerator.

Which elements posses only one electron in their valence shell and what are they called and what is the radioactive element of this group?
These are the alkali metals; the radioactive one is francium (Fr).
How would you describe the elements that are listed after plutonium?
All these elements are man made, metals, radioactive and unstable.
Most radioactive element in transition metals?
Radioactive elements between transition metals: Tc, Rf, Db, Sg, Bh, Hs, Mt, Ds, Rg, Cn.
How do groups on the periodic table compare?
Radioactive elements are in the groups (columns) to the left. On the right, there is non-radioactive metals, gases, and metalloids.
What are polonium and radium?
Radium and polonium are natural radioactive chemical elements, discovered by Pierre and Marie Curie in 1898.

What are the unique properties of actinide metals?
They are mostly Synthetic elements (when nuclear particles are forced to crash into one another by a particle accelerator (machine)). These Elements are Radioactive.

What can be categorized into different types of elements?
Examples: metals or nonmetals, radioactive or not radioactive, classification after the state of matter, reactive or not reactive etc.
What did polonium and radium?
Polonium and radium are natural chemical elements, metals, solid, very radioactive.
Are the elements that make up the iron triad radioactive or are they magnetic or are they alkali metals or are they alkaline earth metals?
There transition, which is the same thing as magnetic
What is the most dangerous element in the transition you?
You think probable to artificial radioactive elements considered transition metals.
What are polonium and radium?
Radium and polonium are natural radioactive chemical elements, discovered by Pierre and Marie Curie in 1898.
Characteristics for uraniums family of elements?
Uranium is a member of the actinoids family. These chemical elements are:- they are considered frequently transition metals- they are radioactive elements- some are artificial elements- they have variable valence
What metal is used in nuclear reactions?
The following metals are involved in nuclear reactions. The preferred metal is Uranium 235. The next one is Plutonium 239. Important radioactive metals are Thorium and Cobalt 60. Important radioactive elements that are not metals include Radon and Iodine.
