Asked in Nuclear Physics
Do all elements have a half-life?
Yes. From a technical point of view, all elements have isotopes (nuclides) that are radioactive and therefore have half-lives. But the majority of these are artificial - man made, and do not occur in nature on Earth. Even hydrogen has nuclides of deuterium and tritium, deuterium is stable and natural, and tritium has a half life of 12.33 years. Having said that, there are a number of nuclides that are stable and occur naturally. ...

What is non-radioactive?
Every stable isotope is non radioactive. That is the definition of "stable." It is possible protons have a half life, but if so it exceeds 6.6 decillion years. Hydrogen and deuterium are stable. Tritium (H3) has a half life of about 12 years. ...
Asked in Chemistry
Does every element has a half life?
Yes, all elements have at least one radioactive isotope. Hydrogen has two isotopes, Deuterium and Tritium. H3 has a half life of 12.3 years. Not all isotopes are radioactive. About half way up the atomic mass table, Tin appears to have the greatest number of stable isotopes - ten out of about 124 isotopes in all. ...

What element is used in nuclear fusion and in what forms?
The element is hydrogen. The easiest reaction to produce on earth (though still very difficult) is between deuterium and tritium. Deuterium is hydrogen with one proton and one neutron, tritium has one proton and two neutrons. Deuterium (heavy water) can be separated from ordinary water whilst tritium has to be made from lithium in a nuclear reactor, and it is radioactive with a half life of 12 years so it does not occur in nature. ...

Why and how Deuterium is responsible for softening of water?
Water is not softened with deuterium.
Why do you see so little deuterium today?
When the Earth first formed, there was an abundant amount of deuterium in the atmosphere. Today, most of the deuterium has fused into helium and because of that, there is little deuterium left. ...
Asked in Physics, Nuclear Energy, Stars, Nuclear Fusion
What is the most common typle of nuclear fusion in the sun?
The most common fusion in the sun is two hydrogen atoms fusing to produce helium. There are different ways this can happen. Two deuterium atoms may fuse, or a deuterium atom may fuse with a tritium atom, or two tritium atoms may fuse. Since the half life of tritium is rather short, the overwhelming majority of these atoms are deuterium atoms. The commonest form of hydrogen, known as protium, does not take part in the process. ...
Asked in The Difference Between
What are the main differences of deuterium and hydrogen?
Deuterium is hydrogen. The difference between deuterium and protium (the regular hydrogen) is that deuterium has an extra neutron. As a result, there are some differences in physical properties such as density, boiling point, etc. ...

The time it takes for half of the radioactive element to decay is the element's what?
That's called the "half-life".
