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.
A radioactive substance will take three half-lives to decay 87.5%.
10 hours
the halflife is 10 days
Radioactive decay.
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).
radioactive 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
no, halflife is a constant for each isotope's decay process.
6 hours. you have a hot one there!
Radioactive decay falls under chemistry, because the chemical properties of the substance are changed during radioactive decay.
okay
The length of time required for half of a sample of radioactive material to decay
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.

They arent really found in the substance, they are a product of radioactive decay.
It indicates how long it takes for the material to decay.
