∙ 12y agoAll elements after element number 83 (bismuth) have only radioactive isotopes. The only two lighter elements that have this property are element 43 (technetium), and element 61 (promethium).
*Bismuth-209 is technically radioactive, but with a half-life of 20 billion billion years (2 x 1019 yrs).

Is americium a radioactive metal?
Yes, americium is a radioactive metal. This element has no stable isotopes.
Does Barium have isotopes that are all radioactive?
Usually not, but all elements have radioactive isotopes.
How many stable isotopes are in the element californium?
All the isotopes of californium are radioactive, artificial and unstable.
Plutonium is a type of lanthanide or actinide or regular transition element?
Plutonium is an actinide
What element is memeber of this group all isotopes of this element are radioactive?

How do an isotopes and a radioactive isotopes ifferent?
Simply by being radioactive or not. An isotope is an atomic variant of the same element, and has the same chemical characteristics, but is not necessarily radioactive.
What element has all of their isotopes radioactive?
