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 half-life of every radioactive element?
The same element can have different half-lives, for different isotopes. You can find a list at the Wikipedia article "List of radioactive isotopes by half-life". This list is NOT complete; a complete list would have about 3000 nuclides (that is, isotopes).
What is the range of half-lives of different radioactive element?
It would be quite difficult to list all radioactive elements and their half lives in this area. Lithium 5 has a half life of about a trillionth of a second. Uranium 238 has a half life of about 4.7 billion years. Since the world is about 4.2 billion years, over half the Uranium 238 is still around. The first element in the Periodic Table, Hydrogen, has a radioactive form, Hydrogen 3. It has a half life of about Twelve and a half years. Helium has a radioactive form, Helium 5. It's half life is a trillionth of a second. Then you get to elements with different radioactive isotopes. You will need to look them up in a handbook. Tin is the element with the most isotopes.
Why does the rate of chemical reaction decrease over time?
Because radioactive substances have half lives. This decreases the radioactivity in the substance.
How many half-lives have carbon gone through if 37245 years have passed and one half-life for carbon is 5730 years?
6.5 half-lives.
What is the problem with disposing of radioactive wastes is that they have a long what?
Radioactive substances have half-lives. This is because the isotope constantly is changing from the radioactive isotope to a daughter element. For example, eventually, when uranium's radioactivity is gone, it becomes lead. After one half life of a radioactive substance, only 50% of that substance is still radioactive. Therefore, after one half-life, a piece of uranium is 50% lead and therefore %50 less radioactive. After another half-life, it has 25% of the original radioactivity, and 75% of the original uranium has become lead. This is the problem with radioactive wastes. It takes many years just for one half lives for some substances, such as uranium. Because radioactivity is harmful, those substances have to be stored until they are no longer radioactive. So, in short, the problem with disposing of radioactive wastes is that they have long half-lives. (although this is not true with ALL substances because some have short half-lives, but, in general, radioactive substances have long half-lives.
Which statement is true about half-lives a Different atoms of the same element have different half-lives. b Each radioactive isotope has its own half-life. c All radioactive nuclides of an element?
The correct answer is: Half-lives are not affected by temperature.
How come elements below uranium have equally short half-lives as the elements above uranium?
This affirmation is not correct; the half lives are different.
The rate at which radioactive decay occur is given in half-lifeexplain the term and give the half-life of a few substances?
A half-life is the time it takes for half of the substance to decay, becoming something else. You can find a list of half-lives in the Wikipedia article "List_of_isotopes_by_half-life".
How many years will it take for one half of the original amount of material to decay?
If you are referring to a radioactive material, that will depend on the material. Different things have very different half-lives.
Which statement is true about half-lives?
A. Different atoms of the same nuclide have different half-lives.B. each radioactive nuclide has its own half-life.C. All radioactive nuclides of an element have the same half-life.D. All radioactive nuclides have the same half-life.
When was How the Other Half Lives created?
How the Other Half Lives was created in 1890.
How The Other Half Lives was created?
How the Other Half Lives was created in 1890.
What is the half life of the radioactive isotope?
The half life is the period of time it takes radioactive decay to transmute one half of the isotope present at the start of the period to a different isotope, usually an isotope of a different element. This period of time is different for different isotopes, with known isotope half lives ranging from femtoseconds to many billions of years.
Half life of the element Sodium?
There are several isotopes of Sodium, each with different half lives. The longest lived, Sodium-22, has a half-life of 2.6027 years.If you are interested in a different isotope, ask the question again and be specific about the isotope in the question.
