The amount left after time t is N = N₀ × (½)^(t/t½). After one half-life half remains, after two a quarter, after three an eighth, and so on.
Mene ne ciwon da ke da tsanani da kuma tsawon rai?
The decay constant is λ = ln2 / t½ ≈ 0.693 / t½, the probability of decay per unit time. The mean lifetime τ = 1 / λ = t½ / ln2 is the average time an atom survives — about 1.44 half-lives.
Can I find the half-life from two measurements?

QShortcut
Any unit, as long as the elapsed time and the half-life share it. Enter both in years, or both in seconds; the ratio t / t½ is all that matters, and the results come back in that same unit.

Multiply by one-half for each half-life: 50% after one, 25% after two, 12.5% after three, 6.25% after four. After ten half-lives under 0.1% remains, which is why "about ten half-lives" is a common rule for effectively gone.

No. It is a fixed property of the isotope, independent of sample size, temperature or chemical state. Whether you start with a gram or a tonne, half decays in exactly one half-life — which is what makes it such a reliable clock.
