In the context of radioactive decay, half-life is the time it takes for half of the radioactive atoms in a sample to decay. This means that after one half-life, half of the original radioactive atoms have decayed, and after two half-lives, three-quarters have decayed, and so on. The concept of half-life helps scientists understand the rate of decay of radioactive substances.
What else can I help you with?
The time it takes for half of the radioactive element to decay is the element's what?
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
What is the characteristic time for the decay of a radioactive isotope?
The characteristic time for the decay of a radioactive isotope is known as its half-life. This is the time it takes for half of the radioactive atoms in a sample to decay.
Do all elements have a half-life?
No, not all elements have a half-life. Half-life is a property of radioactive elements that undergo decay over time. Non-radioactive elements do not have a half-life because they do not decay in the same way.
Define half life of a radiactive element?
The half life of a radioactive element is the time it takes for half of the atoms in a sample to decay. It is a measure of the rate of radioactive decay and is a constant characteristic of each radioactive isotope.
The rate of decay of a radioactive element is measured by its what?
The rate of decay of a radioactive element is measured by its half-life, which is the time it takes for half of a sample of the element to decay. This measurement is used to determine the stability or instability of the element and to predict its rate of decay over time.
When the rate of radioactive decay becomes smaller half life becomes what?
When the rate of radioactive decay decreases, the half-life of the radioactive substance increases. This is because a smaller decay rate means that it takes a longer time for half of the radioactive atoms to decay. Consequently, the half-life, which is the time required for half of the substance to decay, extends as the decay rate diminishes.
Does half-life mean half of somethings lifespan?
It is the amount of time a radioactive atom takes to decay and have half of what its original mass was. Example: an atom has 20g, one half-life later it has 10g, and then 5g and then 2.5, etc.
The time it takes for half of the radioactive element to decay is the element's what?
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
What is the definition of half -life?
All elements have a certain "life-span," until they degrade into either sub-atomic particles, or react with something else. Half-Life is literally the half-point in their life-span.
What is the characteristic time for the decay of a radioactive isotope?
The characteristic time for the decay of a radioactive isotope is known as its half-life. This is the time it takes for half of the radioactive atoms in a sample to decay.
What radioactive element is the time it takes for half of the radioactive atoms to decay?
The half-life
What is half life of a isotope?
The half life of an isotope refers to the rate at which a radioactive isotope undergoes radioactive decay. Specifically, it is the amount of time it takes for half of a given sample of a radioactive isotope to decay.
What is the radioactive half-life of water?
Ordinary water is not radioactive, so it has no half-life.
Do all elements have a half-life?
No, not all elements have a half-life. Half-life is a property of radioactive elements that undergo decay over time. Non-radioactive elements do not have a half-life because they do not decay in the same way.

What is the term given to the time it take for one half of a sample of radioactive nuclei to decay?
The term is called half-life. It is the time it takes for half of the radioactive nuclei in a sample to decay.
