The half-life has a specific value for each isotope.
i got no idea
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
The length of time required for half of a sample of radioactive material to decay
It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.
It tells what fraction of a radioactive sample remains after a certain length of time.
The half-life is the time that it takes for 1/2 of a material to decay.
You forgot to say that isotope is.
The length of time depends on the element and isotope, but the point at which half of the sample has decayed is known as the half-life.
It's called the half-life.
No, the half life remains exactly the same throughout
its called the half-life and it is different for each nuclide.
The rate of decay of a radioactive element cannot be influenced by any physical or chemical change. It is a rather constant phenomenon that appears to be independent of all others. The rate of decay is given by an element's half life, which is the amount of time for approximately half of the atoms to decay.
