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
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 element with the highest half-life is Bismuth-209, with a half-life of approximately 1.9 x 10^19 years.
The half-life of a radioactive element is the time it takes for half of the atoms in a sample to decay. As the sample decays, the number of radioactive atoms decreases while the number of stable atoms increases. The process continues in this manner, with each half-life reducing the amount of radioactive material by half.
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
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.
Ununpentium-288 has a half-life of 173 ms.
Uranium has the longest half-life element
If you mean HALF LIFE, that is the length of time it takes a quantity of a radioactive element to lose half its radioactivity.
