A radioactive element is the element which radiates continuously giving alpha, beta, and gamma rays. The elements having atomic no. more than 82 are mostly considered as radioactive elements. These elements emit radiations by themselves even if if they are not get touched. They are discovered by Maria Curie and Pierre Curie in 1907
What else can I help you with?
What made up all radioactive elements?
After disintegration all radioactive elements are transformed in other elements.
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.
What are the ten elements in thre periodic table that are radioactive?
all elements after uranium (atomic number 92) are radioactive.
Are all elements periodically change to become new element s?
No. Only radioactive elements, which undergo radioactive decay can change to different elements.
Could there be a more elements that are unknown in the periodic table?
sure, but all will be radioactive with short halflives.
Why did Marie Curie discover polonium and radium?
Studying residues of uranium ores, Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
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.
What did Marie Curie discover about radium and polonium?
Marie and Pierre Curie discovered that polonium and radium are natural radioactive chemical elements. Studying residues of uranium ores Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
The pressure and heat that produces magma are caused in part by?

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.
