213At (Astatine) which has a half life of 125 nanoseconds or 0.000000125 seconds.
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
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.
The answer is Radium
No, the half life remains exactly the same throughout
Uranium is a radioactive element and conteneously disintegrate into smaller element, that time in which 1g of uranium becomes half g is known as half life period of uranium.
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 is the time that it takes for 1/2 of a material to decay.
No, the half life remains exactly the same throughout
False- the period is the horizontal row the element is in
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.
The half-life
