What else can I help you with?
What element is memeber of this group all isotopes of this element are radioactive?
There is no group specified so it is not possible to be sure about this answer but all isotopes of promethium are radioactive.
Which element in group 16 has unstable isotopes?
Polonium is the element in group 16 that has unstable isotopes. It is a radioactive element with no stable isotopes.
Is Pm a radioactive substance?
Pm is Prometheum. 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?
An example is uranium.
Does uranium exist in a stable non-radioactive form?
All the isotopes of uranium are radioactive and unstable.
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.
Which lanthanide element and which transition element have only radioactive isotopes?
All or almost all elements have radioactive isotopes if artificial isotopes are included. Among the naturally occurring elements, uranium, polonium, radium, and thorium have naturally occurring radioactive isotopes on earth.
What element that has no stable isotopes?
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.
Is the parent element always radioactive in a nuclear reaction?
No, the parent element in a nuclear reaction is not always radioactive. While many parent isotopes are indeed radioactive and decay into stable or unstable daughter isotopes, there are also stable isotopes that can undergo nuclear reactions without being radioactive themselves. For example, stable isotopes can be involved in nuclear reactions such as neutron capture or fusion, but they do not decay over time like radioactive isotopes.
What are the 2 radioactive isotopes?
There are a lot more than 2 radio active isotopes... To answer this question a naturally or created radioactive element needs to be mentioned.
