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
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.
If the half-life of a radioactive substance is 10 hours how long will it take for 50 percent of it to decay?
The half-life of a radioactive isotope is defined as the time taken for the isotope to decay to half of its initial mass. So to decay to 50 percent of its initial mass will take one half-life of the isotope. One half-life of the isotope is 10 hours so the time taken to decay is also 10 hours.
Does the process of radioactive decay fall under the study of chemistry or physics or is it a combination of both?
Radioactive decay falls under chemistry, because the chemical properties of the substance are changed during radioactive decay.
Half of the total amount of time it takes for all of a radioactive substance to decay is called the halflife of the substance?
okay
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
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.
What is the source of heat in the Earth's interior?
The decay of radioactive isotopes.The decay of radioactive isotopes.The decay of radioactive isotopes.The decay of radioactive isotopes.
Why are alpha beta gamma found in many radioactive substances?
They arent really found in the substance, they are a product of radioactive decay.
What does a half life of a radioactive substance indicate?
It indicates how long it takes for the material to decay.
What does the half life of a radioactive substance indicate?
It indicates how long it takes for the material to decay.
What is it when property describes the ability of a substance to change into different substances?
Radioactive decay.
