What is Half-Life?

The half-life (t₁/₂) of a substance is the time it takes for half of its atoms to undergo radioactive decay or for its concentration to decrease by half. This constant rate of decay is a hallmark of exponential decay processes.

• Initial Amount (N₀): The starting quantity.
• Remaining Amount (N): The quantity after time (t).
• Half-Life (t₁/₂): The time constant for the decay.

Radioactive isotopes like Carbon-14 and Uranium-238 are famous examples where half-life is used for dating and scientific analysis.
