Web1.Hypothesize what half‐lifeis: Half‐life is the amount of time it takes for approximately half of the radioactive atoms in a sample to decay intoa more stable form. Every radioactive element has a different half‐life. 2. Calculate thenumber of radioactive atoms remaining after each half‐life. WebAs you can see, the substance initially has 100% of its atoms, but after its first half life (5 years) only 50% of the radioactive atoms are left. That's what 'half life' means. Literally, half of the substance is gone every five …

WebHalf-life is the period of time it takes for a substance undergoing decay to decrease by half. It is usually 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.
WebExample 2: Find the value of the decay constant of a radioactive substance having a half-life of 0.04 seconds. Solution: Given half life of the substance is t1 2 t 1 2 = 0.04. The half life formula can be used to find the half life of the substance. t1 2 t 1 2 = 0.693/ λ.
