What else can I help you with?
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 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.
Is lithium 8 an isotope why?
Yes, but it has a halflife of only 0.86 seconds.
How do the isotopes of fluorine 18 and fluorine 19 differ?
one neutronfluorine-18 is radioactive undergoing beta+ decay with a halflife of 1.87 hoursfluorine-19 is the only stable isotope of fluorinebeing slightly lighter, fluorine-18 will participate slightly faster in chemical reactions than fluorine-19 willetc.
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.
When an isotope is blank it is radioactive?
When an isotope is unstable, it is said to be radioactive.
What is the stable isotope that is formed by the breakdown of a radioactive isotope?
The stable isotope formed by the breakdown of a radioactive isotope is called a daughter isotope. This process is known as radioactive decay, where a radioactive isotope transforms into a stable daughter isotope through the emission of particles or energy.
Is Cs a radioactive element?
No, it has only one stable isotope.
What type of radiation does P-32 emit?
The radioactive decay of Phosphorus-32 emits only betaparticles (i.e. electrons) with a halflife of slightly longer than two weeks. No electromagnetic radiation at all is emitted.
How is a radioactive isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.
