What else can I help you with?
How many half-lives would be necessary for a sample of parent isotopes to decay to the point that only one-half of the sample is composed of parent isotopes?
It would take one half-life for a sample of parent isotopes to decay to the point where only one-half of the sample is composed of parent isotopes. Each half-life reduces the amount of parent isotopes by half.
Who describes an isotopes half life?
Half-life is described in time units.
What is the half life of arsenic?
Arsenic (in the form of arsenic-75) is a stable element. Only its isotopes have a half-life. As there are many isotopes of every element, and each has a different half life, it is difficult to specify a precise answer. The related link below contains a list of known isotopes and their half lives.
Why do fewer isotopes decay in each successive half life?
Because each amount is halved over the time it takes for the half life process for instance A Isotope has a half life of 20 years If it starts off with 12,000 then in 20 years it'll be 6,000 (halfed) another 20 years it'll be 3,000 so no matter how much there are, it will always decrease by half
What is the uses of isotopes in your daily life?
isotopes is a type of i guess calorie like things you need 4 grams of IT (isotopes) every day
State what is meant by half life of radioactive isotopes?
This is the time in which half the the atoms was disintegrated.
What is the half-life of plutonium-239?
Plutonium has 20 isotopes; each isotope has another half-life. Please read: http://en.wikipedia.org/wiki/Isotopes_of_plutonium.
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).
How many unstable isotophes are in xenon?
The number of unstable isotopes cannot be determined. Xenon has 9 stable or primordial isotopes. These include isotopes whose half-life is greater than 80 million years which is long enough for some of the atoms to have survived. It is also possible that so-called stable isotopes are not really stable but have half-lives of more than 10^22 years.Of the 9 Xenon isotopes,134Xe has a half-life of 1.1*10^16 years;136Xe has a half-life of 8.5*10^21 years;124Xe has a half-life of 1*10^17 years.
What is gamma half life?
Most gold is made up of isotopes that have never been observed to undergo radioactive decay and therefore has no known half-life. Some synthetically prepared isotopes of gold may be radioactive and thus have a half-life, the length of which would depend on the particular isotope.
Among the following radioactive parent isotopes, which has the shortest half-life?
The radioactive parent isotope with the shortest half-life among the options provided.
What is the calculation of radioactive isotopes?
Examples characteristics: half life, specific activity, radiotoxicity.
