Is lithium 8 an isotope why?
Yes, but it has a halflife of only 0.86 seconds.
Is it possible to determine exactly when a particular unstable isotope will begin to decay?
No. The time it will take for an individual unstable atom to decay is completely random and impossible to predict. However, because there are so many atoms in a sample (6.02x1023 in one mole) it is possible to observe the half-life of the atoms. The half-life is the time that it will take for half of the atoms in a sample of a radioactive isotope to decay into another element or isotope. This is a constant property of the isotope and does not depend on the sample size.
What is the time needed for half of a sample of a radioactive isotope to break down to form daughter isotopes called?
halflife
All radioactive nuclides of an element have the same half life?
No, halflife is a bulk statistical property of a quantity of an isotope of an element.Individual nuclei do not have halflives, instead they have a probability of decaying at the current moment of time.
What happens to the amount of parent isotope in a rock with time?
The amount of parent isotope in a rock decreases with time as it decays into daughter isotopes. This is known as radioactive decay, and the rate of decay is constant for a particular parent isotope. By measuring the ratio of parent to daughter isotopes, scientists can determine the age of the rock using radiometric dating techniques.
Is lithium 8 an isotope why?
Yes, but it has a halflife of only 0.86 seconds.
Is it true that the half-life of a radioactive isotope decreases as the isotopes decay?
no, halflife is a constant for each isotope's decay process.

Is any isotope of lead is radioactive?
many. one example is lead-214 with a halflife of 26.8 minutes.
What is the time needed for half of a sample of a radioactive isotope to break down to form daughter isotopes called?
halflife
How do you compute a halflife?
There is no simple formula to determine the half life of every single radioactive isotope. However, y = A(.5)^t/h, where A=staring amount, t=time, and h= half life, is a general equation that usually works well.
How do scientists use the halflife of radioactive isotopes to date rocks and fossils?
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
How does uranium 234 behave?
Uranim-234 is a rare natural isotope of uranium - the abundance is 0,0054 %.This isotope ha 92 protons, 142 neutrons and an atomic mass of 234,040 952 1(20).His halflife is 245 500 years.
How can one determine the natural abundance of an isotope?
One can determine the natural abundance of an isotope by analyzing the ratio of the isotope to the total amount of that element in a sample using techniques such as mass spectrometry or nuclear magnetic resonance spectroscopy.

How is the importance of half-life an important consideration surrounding the use of nuclear power storage of nuclear waste?
The halflife of a particular isotope simply tells how long it will remain dangerously radioactive. By storing the spent fuel rods on site much of the shorter lived more intense radiation will have decayed before moving it to a long term repository.
