213At (Astatine) which has a half life of 125 nanoseconds or 0.000000125 seconds.
The shortest half-life of any known radioactive element is that of francium-223, which is approximately 22 minutes.
The radioisotope with the shortest half-life among the following options is Polonium-214.
The radioactive parent isotope with the shortest half-life among the options provided.
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
The answer is Radium

Half life of an element can't be changed.. It is a characteristic of a radioactive element which is independent of chemical and physical conditions.. Half life is that time in which half of radioactive sample( i.e., a radioactive element) decomposes. So no matter what amount you take half life of an element remains same.
The answer is Radium
The half-life of an element is the time it takes for half of a sample to decay. It is specific to each element. The half-life of carbon-14 is 5730 years, whereas the half-life of element Z would depend on the specific element and is not necessarily comparable to carbon-14.
The half-life is the time that it takes for 1/2 of a material to decay.
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.
Without knowing the element and the specific isotope, this has no answer.
Uranium has the longest half-life element
Ununpentium-288 has a half-life of 173 ms.
