    The half-life of radon-220 is \approx imately 55.6 seconds.

    Half-life is a measure of the time it takes for half of a given quantity of a radioactive substance to decay. In the case of radon-220, this means that if you started with a sample of 1000 radon-220 atoms, after 55.6 seconds, you would have \approx imately 500 remaining. After another 55.6 seconds, you would have \approx imately 250 remaining, and so on.

    Radon-220 is a radioactive isotope of radon, a colorless, odorless, and tasteless noble gas that is formed by the decay of radium-224. Radon-220 itself decays by alpha particle emission, meaning it releases a helium nucleus, to become an isotope of polonium. Due to its short half-life and alpha particle emission, radon-220 is highly radioactive and poses a health risk if inhaled.
