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.
How would you describe the isotopes of hydrogen?
All atoms of a specific element have the same number of protons in their nucleus, but the number of neutrons in the nucleus may vary these are isotopes of that element.Hydrogen has several possible isotopes, only the first three of these are commonly referred to:hydrogen or protium or hydrogen-1, 1 proton 0 neutrons, stabledeuterium or hydrogen-2, 1 proton 1 neutron, stabletritium or hydrogen-3, 1 proton 2 neutrons, radioactive halflife 12.26 yearshydrogen-4, 1 proton 3 neutrons, radioactive halflife about 139 yoctosecondshydrogen-5, 1 proton 4 neutrons, radioactive halflife about 910 yoctosecondshydrogen-6, 1 proton 5 neutrons, radioactive halflife 290 yoctosecondshydrogen-7, 1 proton 6 neutrons, radioactive halflife 23 yoctosecondsetc.
What is the time needed for half of a sample of a radioactive isotope to break down to form daughter isotopes called?
halflife
What if your cat is radioactive with the same halflife as carbon 14. how many years will it take for three fourths of your cat to degrade?
my grandma
How do you determine the half life of a radioactive substance that has changed through radioactive decay After 40 days the original substance left is is one sixteenth of the original amount?
the halflife is 10 days
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.
A list with explanation of at least 3 medical medical uses of radioactive materials?
The explanation is the effect of ionizing radiation on tissues and materials.Three uses are:- sterilizing of instruments and parapharmaceutic items- diagnostic with radioactive isotopes (scintigraphy)- treatment of cancers with radioactive isotopes
How does the length of the half-life of the element correspond to the radioactivity of the element?
The length of time required for half of a sample of radioactive material to decay
What kind of process is radioactive decay?
It is a nuclear process.
When radioactive isotopes break down into other elements the process is called?
radioactive decay
What is halflife about?
Half-life is the time it takes for one half of the radioactive material to decay. It is logarithmic, so after two half-lives, one quarter remains - then one eighth - etc.
