i guess it's Tellurium 128, with a half life of 2.2e24; you may consider it a stable isotope as well.
Hydrogen. It's half life is infinity!
Uranium
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.
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.
No, the half life remains exactly the same throughout
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.
False- the period is the horizontal row the element is in

The answer is 2. If after one half-life only half of the element remains, then after another half-life half of what was there only remains. So a half of a half is a quarter (or a fourth). So that's 2 half-lives.
Half-life time of a radioactive element is the time required for the decomposition of half of the actual mass of the element."Half life of radon is 3.8 days."This means that a particular mass of radon is reduced to half its mass in 3.8 days. The half-life period of an element does not depend upon the original mass of the element. This means that 10gms of radon will become 5gms of radon is 3.8 days, and 80gms of radon will become 40gms in 3.8 days.
The half life is the period of time it takes radioactive decay to transmute one half of the isotope present at the start of the period to a different isotope, usually an isotope of a different element. This period of time is different for different isotopes, with known isotope half lives ranging from femtoseconds to many billions of years.
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.
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 half-life is the time that it takes for 1/2 of a material to decay.

Without knowing the element and the specific isotope, this has no answer.
