The half-life of a quantity whose value decreases with time is the interval required for the quantity to decay to half of its initial value. The concept originated in describing how long it takes atoms to undergo radioactive decay but also applies in a wide variety of other situations.
Half-lives are very often used to describe quantities undergoing exponential decay-for example radioactive decay-where the half-life is constant over the whole life of the decay, and is a characteristic unit (a natural unit of scale) for the exponential decay equation. However, a half-life can also be defined for non-exponential decay processes, although in these cases the half-life varies throughout the decay process. The converse for exponential growth is the doubling time.
It's more in physics than chemistry but a half-life it the time taken for half the radionucleii in a radioactive substance to decay.

Chemistry, our life our future. Chemistry is the building blocks of everything.
It is sort of. If you include organic chemistry it is all about the studies of chemistry in life and is related to the environment.
Principally, the chemistry of life is the chemistry of carbon.
Chemistry plays a vital role in people's lives. All characteristics that define life are governed by the laws of chemistry. Without these chemical reactions, life will not be sustained.
nothing chemistry is stupid
In chemistry, the half-life of a reaction is defined as the time needed for the concentration of a reactant to decrease to half of its initial concentration. According to that definition, the half-life of the reaction will be t1/2 = 0,693/k where k is the equilibrium constant for that reaction at a specific temperature.
