What is the radioactive half-life of water?
Ordinary water is not radioactive, so it has no half-life.
What happens to radioactive materials if you do not use them?
That depends on the radioactive material. But whether you use it or not, the radioactive material will decay into other elements over the course of time. The time it takes for half of the material to decay into something else is called the "half-life". The more radioactive the substance is, the faster it decays. The half-life of a radioactive element can be measured from fractions of a second to billions of years.
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.
How does half life work in the context of radioactive decay?
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 happens to the mass of a sample containing a radioactive element during its half-life?
Chawad says... They are directly proportional
What radioactive element is the time it takes for half of the radioactive atoms to decay?
The half-life
What is the half life of an isotope?
The half-life of a radioactive isotope is the amount of time it takes for one-half of the radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by conditions and is independent of the initial amount of that isotope.
What is the half- life of radioactive carbon?
Carbon-14 or 14C, which is a radioactive isotope of carbon, has a half life of 5,700 years.
What is the radioactive half-life of apple pie?
I'm sorry, but apple pie does not have a half-life. You have to be radioactive to have a half-life. If apple pie was radioactive, half of the world would have 7 toes or legs growing out their backs. All of the above is lies
How do radioisotopes of an element differ feom other isotopes?
Radioisotopes are "radioactive isotopes"; they are not stable. Radioactive atoms will decay, or break apart into other atoms, by emitting an electron, or a neutron or a positron or an alpha particle (2 protons and two neutrons). The rate at which this happens is measured by the "half-life"; after one half-life, half of the atoms will have decayed. After another half-life, half of the remaining atoms will have decayed. Atoms with short half-lives are highly radioactive, and can be fairly dangerous. Atoms with long half-lives are only slightly radioactive, and aren't all that dangerous.
Best definition of half-life for a radioactive substance?
The half-life of a radioactive substance is the time it takes for half of the atoms in a sample to decay. It is a constant characteristic of each radioactive isotope. After one half-life, half of the original substance will remain, and the other half will have decayed into other elements.
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.
