∙ 12y agoAll the elements from atomic number 84 [Polonium (Po)]and onwards are radioactive. Also, elements with atomic numbers 43 and 61 (Technetium and Promethium) are radioactive. If an element is radioactive, it means it's nucleus is likely to decay into another element.

What are monoisotopic elements?
Mono isotopic elements are stable isotope of an element.From 80 isotopic elements there are 26 radioactive elements discovered up till now.These mono isotopic may or may not be radioactive if they are radioactive they have halve lives.
Are synthetic elements radioactive?
Synthetic elements are usually radioactive, but not necessarily so. It is conceivable for a non-radioactive neutral atom to be produced by a nuclear spallation reaction.
Which element is radioactive and synthetic?
All transuranic elements are synthetic and radioactive.
What elements give off particles?
the unstable elements in periodic table is Radium because it always leave the radio active waves so it lost its mass slowly slowly all radio active elements are unstable. Any thing more By Varun
What is unique about element 89-112?
Elements 89-112 are radioactive elements.
Radioactive elements comprise a majority?
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.
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.
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.
Can one element change into a different element?
Yes, but only if it is radioactive. Radioactive elements change into different elements through radioactive decay.
What types of elements are useful for dating materials?
Radioactive elements are used to date the age of rocks. Radioactive elements decay according to a known pattern. Scientists can use the elements of that pattern to determine when the rock with the original radioactive element was formed.
How many artificial elements are not radioactive?
None - they are all radioactive.
Is hydrogen an radioactive?
Usually not, but all elements have radioactive isotopes.
Can a natural isotope be radioactive?
Yes; some of the naturally occurring isotopes of the heaviest elements are radioactive.
