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.

∙ 12y agoThe term only makes sense for unstable (radioactive) nuclides.
All elements do have radioactive nuclides, though some don't have any stable nuclides.
It's also just barely possible that protons are not stable over the extremely long term, though if so their half-lives are much, much longer than the current age of the universe. If this is true, then all elements are technically "radioactive."

∙ 13y agoNo, all radioactive elements do not have the same half-life. The range of element half-lives is enormous. At one extreme, there might be an isotope like astatine-213, which has a half-life of about 1.25 x 10-7 seconds (125/1,000,000,000ths of a second, or 125 nanoseconds). At the other are elements such as uranium-238, which has a half-life of 4.468 × 109 years (about 4.4 billionyears). And believe it or not, these do not represent the shortest and longest half-lives of isotopes we know of.

∙ 13y agoYes. 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.

∙ 11y agoYes of course, all radioactive elements are supposed to have half-lives
Wiki User
∙ 12y agoHalf life is when half of an element decays. Yes, I believe all elements have half-lives but I'm not quite sure. If you want to know ask your science teacher.

Do radiotracers generally have long or short half-lives?
Radiotracers generally have short half lives. Detection requires a number of decay events. Using material with a short half life means a smaller amount is required and that after the detection the amount of residual radiation is reduced.
Why do all isotopes have the same chemical?
All Isotopes have the same chemical properties because: * they all have the same electrons in the OUTERMOST shell. * they all have the same electronic configuration.
What do all carbon isotopes have in common?
All carbon isotopes have the same number of neutrons.
What is the half life of a radioistope?
The half-life of every isotope is different. Some elements and isotopes have half-lives in millions of years, while some elements have half-lives measured in milliseconds. You can look up all of the specifics for any element at webelements dot com.
What is the same about isotopes and atom?
All the isotopes of an atom have the same number of protons but different number of neutrons.
Are regular isotopes originaly stable?
Some natural isotopes are stable or have half-lives greater than the age of the Universe. But other natural isotopes are radioactive and have finite half-lives. It all depends on the particular isotope.
To find the halflife period of curium?
For the half lives of all curium isotopes see the link below.
Is astatine odorless?
All the isotopes of astatine are radioactive and has very short half lives; consequently is a dangerous element.
Is osmium radioactive?
Osmium is very weakly radioactive. There are seven naturally occurring isotopes of osmium, four of which are stable. The three radioactive isotopes all have very long half lives, but they account for 42.39% of it.
Can all radioactive isotopes be used in radiometric dating?
No, not all radioactive isotopes be used in radiometric dating. Some have very very short half lives and would entirely disappear before any useful period of time passed.
Which element is most radioactive plutonium uranium or cerium?
All the isotopes of uranium and plutonium are radioactive; plutonium isotopes have a greater specific activity. For cerium: the isotopes 136Ce and 142Ce are possible to be radioactive but having very long half lives and a not significative radioactivity.
Do radiotracers generally have long or short half-lives?
Radiotracers generally have short half lives. Detection requires a number of decay events. Using material with a short half life means a smaller amount is required and that after the detection the amount of residual radiation is reduced.
Why do all isotopes have the same chemical?
All Isotopes have the same chemical properties because: * they all have the same electrons in the OUTERMOST shell. * they all have the same electronic configuration.
How many half lives does it take for half of a radioisotope to dissipate?
It depends on the radioisotope. They do not all have the same half life.
What do all carbon isotopes have in common?
All carbon isotopes have the same number of neutrons.
What is the same about isotopes and atom?
All the isotopes of an atom have the same number of protons but different number of neutrons.
