All the isotopes of promethium are radioactive.
The most important isotope of promethium is Pm-147.
All promethium isotopes are radioactive.
It is impossible, promethium is highly radioactive.
A radioactive element is one that does not have a stable occurring isotope. Some of these elements include astatine, radon, technetium, promethium and so many more.
Promethium is not in the neptunium series of radioactive decay.
Isotopes do not stop decaying. The process of radioactive decay continues until the isotope reaches a stable state, which could be a different isotope or a non-radioactive element. The rate of decay can vary depending on the specific isotope.
Yes, Promethium is a radioactive element that is paramagnetic, meaning it is weakly attracted to magnetic fields.
As a radioactive material promethium is dangerous by ingestion, inhalation or skin contact.
The atom of promethium contain 61 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
The atom of promethium contain 61 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
Promethium has 61 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
Answerelements with a nonstable isotope or at least one naturally occurring isotope that is radioactive. AnswerAll elements have radioactive isotopes.There are a lot of radioactive elements: Technetium, Promethium, Polonium, Astatine, Radon, Francium...Here is the whole list: http://periodictable.com/Elements/Radioactive
