How uranium nucleus become stable?
Being radioactive, uranium is not a stable element.
What element continue to decay until they finally become stable?
All elements above the atomic number of 83 are radioactive, but two elements that are under it are also radioactive. They are technetium (atomic number 43) and promethium (atomic number 61). Radioactive elements are elements that decay until stable. =)
Which element is a stable element?
A stable element is any non-radioactive element. All elements before element atomic number 84 (not including 84) - Polonium (Po) are stable elements.
Can a radioactive element completely decay so that it is all stable matter?
A radioactive element (atom) can decay up to a stable isotope.
What is the first radioactive element number?
Of elements that have no stable isotopes, technetium has the lowest atomic number, which is 43.
Is americium a stable nonradioactive element?
No, americium is an unstable and radioactive chemical element.
Is astatine an example of radioactive element?
Yes. There are no stable isotopes of astatine, they are all radioactive.
Is americium a radioactive metal?
Yes, americium is a radioactive metal. This element has no stable isotopes.
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.
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.
Sodium Na 11 stable or radioactive?
Sodium Na 11 is a stable element.
Is Cs a radioactive element?
No, it has only one stable isotope.
