In a chemical reaction, the half-life of a species is the time it takes for the concentration of that substance to fall to half of its initial value. In a first-order reaction the half-life of the reactant is ln (2)/λ, where λ (also denoted as k) is the reaction rate constant.
Learn about half-life, the time it takes for half of a radioactive sample to decay, and how it varies for different types of decay. Also, explore nuclear reaction, the change in the identity or characteristics of an atomic nucleus by bombarding it with an energetic particle.

The Half-Life saga is the story of Gordon Freeman, a physicist who finds himself at the center of resistance to an alien invasion that threatens the future of humanity. From Valve's 1998 debut game onward, the series has been at the forefront of immersive action and storytelling.
The half-life of a reaction (\(t_{1/2}\)), is the amount of time needed for a reactant concentration to decrease by half compared to its initial concentration. Its application is used in chemistry and medicine to predict the concentration of a substance over time.
