What else can I help you with?
Is lead radioactive?
Yes, lead is a stable element and is not considered radioactive.
How uranium nucleus become stable?
Being radioactive, uranium is not a stable element.
What is the name of the time required to change a part of a radioactive element to a stable element?
The name for the time required for half of a radioactive element to decay into a stable element is called the half-life. It is a constant value unique to each radioactive isotope, and it is used to measure the rate of radioactive decay.
Is the element thulium radioactive or non-radioactive?
Thulium is a non-radioactive element. It is part of the lanthanide series on the periodic table and has no stable isotopes that are radioactive. Thulium-169, the most common isotope, is stable and does not undergo radioactive decay. Therefore, thulium is considered non-radioactive.
Is americium a stable nonradioactive element?
No, americium is an unstable and radioactive chemical element.
Is americium a radioactive metal?
Yes, americium is a radioactive metal. This element has no stable isotopes.
Is astatine an example of radioactive element?
Yes. There are no stable isotopes of astatine, they are all radioactive.
Does uranium exist in a stable non-radioactive form?
All the isotopes of uranium are radioactive and unstable.
What does it mean if an element is radioacitive?
If an element is radioactive, it refers to the stability of their atomic nucleus. If that atomic nucleus is not stable, it is considered radioactive.
Is Cs a radioactive element?
No, it has only one stable isotope.
Is radon a stable radioactive element?
Radon is radioactive and is actually a fairly common hazard because of this.
If you had a stable element 115 could you then have an isotope of it that would be non-radioactive?
If you had a stable element 115, then by definition there would need to be at least one non-radioactive isotope. Stable elements are those that have at least one nonradioactive isotope. Of course, the other isotopes of the element could all be radioactive.
