The length of time required for half of a sample of radioactive material to decay
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 can vary from tiny fractions of a second to several sextillion years.
Most gold is made up of isotopes that have never been observed to undergo radioactive decay and therefore has no known half-life. Some synthetically prepared isotopes of gold may be radioactive and thus have a half-life, the length of which would depend on the particular isotope.
No, the length of time required for half of the radioactive atoms in a sample to decay is its half-life, not period. The half-life is the amount of time it takes for half of the radioactive atoms in a sample to undergo radioactive decay. Period typically refers to the time it takes for a complete cycle of a repeating event.
This is called the "half-life" of the isotope.

The time it takes for half of a radioactive sample to decay is known as the half-life. Each radioactive element has a unique half-life, which could range from fractions of a second to billions of years. The half-life remains constant regardless of the size of the initial sample.
The length of time required for half of a sample of radioactive material to decay
It tells how long it takes for a radioactive isotope to become a daughter element.
It tells what fraction of a radioactive sample remains after a certain length of time.

It tells what fraction of a radioactive sample remains after a certain length of time.
It can vary from tiny fractions of a second to several sextillion years.

This is its half-life.
