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 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.
How long is berkelium's half- life?
The half life of the most important isotope of berkelium - 247Bk - is 1 380 years.
What is the Half life of penicillin?
The half-life of penicillin varies depending on the specific type. For example, the half-life of penicillin G is typically around 30 minutes to 1 hour in the body. Penicillin V, another common type, has a slightly longer half-life of around 1 hour to 1.5 hours.
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 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

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!
How long does it take to hatch Ghazt in your Singing Monsters?
It takes 1 day and 12 hours of 1 day and a half to hatch a Ghazt
How much is three times a half life?
Three times a half-life is equivalent to one and a half full life cycles of a substance. In terms of decay, after three half-lives, only one-eighth of the original amount remains. This is because each half-life reduces the amount by half, so after three halvings (1/2, 1/4, 1/8), the remaining quantity is 1/8 of the initial amount.
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%

What is Alli half life?
The half-life of Alli (orlistat) is around 1 to 2 hours. This means that it takes about 1 to 2 hours for half of the drug to be eliminated from the body.
