half life
Yes, lead is a stable element and is not considered radioactive.
NO!!! Because if it was, there would not be any silver jewellery/cutlery etc., about, because the radio-activity woulkd be dangerous.
When a radioactive element decays, it releases energy in the form of radiation (such as alpha or beta particles). The decay changes the element into a different element or isotope, which may also be radioactive. This process continues until a stable non-radioactive element is formed.
Technetium (Tc) is the element that has no stable isotopes. All of its isotopes are radioactive with half-lives ranging from minutes to millions of years.
A stable element is any non-radioactive element. All elements before element atomic number 84 (not including 84) - Polonium (Po) are stable elements.
A radioactive element (atom) can decay up to a stable isotope.
Yes, lead is a stable element and is not considered radioactive.
Being radioactive, uranium is not a stable element.
No, americium is an unstable and radioactive chemical element.
Yes, americium is a radioactive metal. This element has no stable isotopes.
Yes. There are no stable isotopes of astatine, they are all radioactive.
All the isotopes of uranium are radioactive and unstable.
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.
No, it has only one stable isotope.
Radon is radioactive and is actually a fairly common hazard because of this.
This is an element (more exactly an isotope) which is not radioactive.
All the isotopes of nobelium are radioactive and unstable.
