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.

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
What is it when property describes the ability of a substance to change into different substances?
Radioactive decay.
What is the longest radioactive halflife?
First, it isn't very accurate to talk about a radioactive "element"; you should talk about radioactive isotopes. Different isotopes of the same element can have very different behavior in this sense. For example, hydrogen-1 and hydrogen-2 are stable, while hydrogen-3 is not (half-life about 19 years).Individual atoms, in a radioactive isotope, will decay at a random moment. The half-life refers to how long it takes for half of the atoms in a given sample to decay (and convert to some other type of isotope).
When radioactive isotopes break down into other elements the process is called?
radioactive decay
Is radioactive decay the same as organic decay?
No, radioactive decay is not the same as organic decay. The basic difference between radioactive decay and organic decay is that in organic decay, chemical compounds break down and the biochemical structure of the subject changes. This is a natural process that any biological structures will undergo, or it could be induced. In either case, it represents a chemical change. In radioactive decay, the actual atomic nuclei of atoms will break down in some way, depending on the substance being considered. It is the unstable atomic nucleus of given isotopes of elements that undergoes the change, and this is a nuclear or atomic change.

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.
What is a half-life of radioactive substance if it takes 6 hours for 50 percent of it to decay?
6 hours. you have a hot one there!
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.

Why are alpha beta gamma found in many radioactive substances?
They arent really found in the substance, they are a product of radioactive decay.
