How is the half life of an isotope defined?
A half-life is the time taken for the radioactivity of a material to fall to half its original value. A material can undergo infinite half-lives because each time it falls to half the next half-life falls to half of that half: No half-lives have elapsed when radioactivity is at the original amount; 1/1. 1 half-life is when radioactivity is at 1/2 2 half-lives is when radioactivity is at 1/4. 3 half-lives is when radioactivity is at 1/8. 4 half-lives is when radioactivity is at 1/16. And so on.
What fraction of a radioactive sample remains after one half-life?
Half of the original sample of a radio isotope remains after a half-life period. After two half-life periods, one-fourth of the radio isotope remains.
If the half-life of a radionuclide is 1 month is a sample of it completely decayed after 2 months?
No, it is not. If a radionuclide has a half-life of 1 month, half is gone after 1 month. Half of the half that is left will be gone after 2 months, and that will leave 1/4th of the original amount left after the second month.
How long is berkelium's half- life?
The half life of the most important isotope of berkelium - 247Bk - is 1 380 years.
Is the half-life of a chemical element one-half of the amount of a radioactive element to decay?
The half-life is the time that it takes for 1/2 of a material to decay.
When did Action Half-Life happen?
Action Half-Life happened in 1999.

What approximate amount of the element remains after 3 half-lives have elapsed?
1/8 amount of the element will reamain. After 1 half-life there is 1/2 left After the 2nd half-life there is 1/2 of 1/2 left which is 1/4 After the 3rd half-life there is 1/2 of 1/4 left which is 1/8
What fraction of a radioactive sample remains after one half-life?
Half of the original sample of a radio isotope remains after a half-life period. After two half-life periods, one-fourth of the radio isotope remains.
How do you import half life 1 weapons into half life 2?
Buy Half Life: Source Or Buy Garrysmod a Half-Life 2 Modification and get the addon "Half-Life Rennaisance" Link to Half Life Rennaisance: http://www.garrysmod.org/downloads/?a=view&id=57033 Enjoy!

Are any of Jacqueline Wilson's storys happened in real life?
yes well some of her books are real life some are not some books are even half real half made up
How long is berkelium's half- life?
The half life of the most important isotope of berkelium - 247Bk - is 1 380 years.
How much original matter remains after 9 hours if the matter has a half-life of 3 hours?
A half-life means half the original matter decays and is gone after that period. Something with a 3 hour half-live will have only 1/2 its amount left after 3 hours. After 6 hours, only 1/4th is left, and after 9 hours, only 1/8th is left. After one half-life, half is gone. Half is left. After another half-life, half of the remaining half is gone, leaving one quarter left. After the third half-life, half of the quarter is gone and half of that quarter remains, which is an eighth of the original.
Is the half-life of a chemical element one-half of the amount of a radioactive element to decay?
The half-life is the time that it takes for 1/2 of a material to decay.
What games does the orange box for ps3 have on it?
Half Life 2 Half Life 2: Episode 1 Half Life 2: Episode 2 Portal Team Fortress Hope this helps ;)
What percentage of a radioactive element will be left after 1 half-life?
Half life is pretty much self explanatory in that after they go through 1 half life half of the radioactive decay remains. 1/2 x 1/2 x 1/2 = 1/8 = 0.125 = 12.5% or you can divide 100% by 2, 3 times and you'll get 12.5%
