The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.

The amount of time required by half the nuclei in a sample of radioactive isotope to decay is called its Half life.

Half life
Half-life
It tells what fraction of a radioactive sample remains after a certain length of time.
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.
Time it takes for half of the atoms in a shape to decay!
The half-life of a radioactive element is the time required for one-half of the nuclei of a radioisotope sample to decay to products.Half-life (t½) is the time required for a quantity to fall to half its value as measured at the beginning of the time period.
Radiation in Alpha Particles, Beta Particles, Or Gamma Rays, Its Measured in Half-lifes; Which, put simply, is the time it takes for the element to decay half of its radioactivity away
i got no idea

The half-life
It varies from one element to another. It is measured in terms of its half-life. A half-life is the length of time it takes for half the number of radioactive atoms of the element in a lump to decay.
It really applies to radioactive isotopes, not elements. An element may have different isotopes, some of which are radioactive, some not.The half-life is the time it takes for half of a sample to decay - for the atoms to convert to some other type of atom.
The half-life is the time that it takes for 1/2 of a material to decay.
Half-life
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.
It tells what fraction of a radioactive sample remains after a certain length of time.
To figure out how old something is based how long it takes elements in the sample to decay.
