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 was Marie Curie's important contribution to science?
Isolation of the radioactive 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.
What made up all radioactive elements?
After disintegration all radioactive elements are transformed in other elements.
A mineral that is radioactive probably contains the element?
Any of a variety of elements might do for this, including thorium and uranium, but even potassium has an important radioactive isotope 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 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.
