Decay constant formula

The decay constant is a key concept in understanding how unstable atoms, or radioactive materials, lose their energy and transform into different elements over time. It represents the probability of decay of a single atom per unit of time. In simpler terms, the decay constant helps us calculate how quickly a radioactive substance will decrease in amount. It is usually denoted by the symbol λ (lambda) and is used in formulas to determine the remaining quantity of a substance after a certain period, reflecting how quickly the substance "decays" or transforms.
