yes they do
They can be used in estimating the age of an object by measuring its half lifes.
No, not all elements have a half-life. Half-life is a property of radioactive elements that undergo decay over time. Non-radioactive elements do not have a half-life because they do not decay in the same way.
Because the isotopes do not appear in equal amounts. This is hardly surprising since many isotopes experience radioactive decay and change to other elements after decay while stable isotopes persist - thus stable isotopes will usually dominate as the most common isotopes for individual elements with those with the longest half-lifes being more common than those with shorter half-lifes. Of course when you get into the heaviest elements there don't seem to be any stable isotopes so those with longest half life dominate.
To determine the half-life of an element, scientists conduct experiments to track the decay of a radioactive substance over time. They measure the time it takes for half of the unstable atoms in the sample to decay into more stable forms. This half-life value is a characteristic property of each radioactive element.
love.
we know there will be an epiode 3 but we dont know anything else
NCHOPS - Nitrogen, Carbon, Hydrogen, Oxygen, Phosphorus, Sulfur
All elements have a useful purpose, including the synthetic actinides that have half-lives measured in milliseconds.
Each isotope has a different rate of radioactive disintegration characterized by the half-life, the time necessary to reduce by half the number of atoms.
Well yes but she has two lifes so half real half not
After 3 half lifes there will 45 counts per hour (360 -> 180 -> 90 ->45). Therefore 3 half lifes equals 18 hours. One half life is therefore 6 hours.
Chances are that the elements have gotten old and the deterioration has caused it to heat up only to half power. New elements will run you around $25 each. (Depending on stove)
