There are a lot of radioactive elements:
Technetium, Promethium, Polonium, Astatine, Radon, Francium...
Here is the whole list: http://periodictable.com/Elements/Radioactive
What else can I help you with?
Are synthetic elements radioactive?
Some synthetic elements are naturally radioactive due to their unstable atomic structures. For example, elements beyond uranium on the periodic table are typically artificially produced and tend to be radioactive. These elements can emit radiation as they undergo radioactive decay.
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
All isotopes of this element are radioactive?
Radioactive Elements (38) These elements are radioactive. They either have no stable naturally occurring isotope, or else are entirely artificial (all artificial elements have no stable isotopes). by Andrew Moore
What alkaline earth metal is radioactive?
There are two radioactive alkaline earth metals: radium (Ra) and radium (Ra). Both elements have radioactive isotopes that undergo radioactive decay.
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.
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.
Radioactive elements comprise a majority?
Radioactive elements make up a small fraction of all naturally occurring elements in Earth's crust. Most elements are stable and non-radioactive. However, even though they are a minority, radioactive elements play important roles in various scientific, medical, and industrial applications.
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 are elements with no stable isotopes called?
Elements with no stable isotopes are called radioactive elements. These elements spontaneously undergo radioactive decay, which leads to the formation of stable isotopes over time.
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.
Are synthetic elements radioactive?
Some synthetic elements are naturally radioactive due to their unstable atomic structures. For example, elements beyond uranium on the periodic table are typically artificially produced and tend to be radioactive. These elements can emit radiation as they undergo radioactive decay.
What family is made up of all radioactive elements?
The family of radioactive elements is called the Actinides. This group includes elements such as uranium, thorium, and plutonium, which are known for their radioactive properties.
Is hydrogen an radioactive?
Usually not, but all elements have radioactive isotopes.
