See the discussion on half-life here.onqun said:Hello, I am curious. Eventhough, the half-time of an element is always the same. Why not we can't find quarter of elements vanish time, because; half life is directly proportional, 10gr 10 min -> 5gr 20min. if 10 gr vanishes in 10 min, 2.5gr vanishes in 2.5 min for 20gr radioactive material.

one half-lifeHalf-Life Decay is a radioactive decay process that occurs when an unstable atom releases energy in the form of radiation in order to become more stable.
Half-Life Decay is caused by the unstable nucleus of an atom that has an excess of either protons or neutrons, which makes it unstable and prone to decay.
The Half-Life of a substance is determined by measuring the amount of time it takes for half of the original amount of an unstable substance to decay into a more stable form.
Half-Life Decay can have both positive and negative effects on the environment. It is used in various fields such as nuclear medicine and energy production, but it can also have harmful effects on living organisms if they are exposed to high levels of radiation.
No, Half-Life Decay cannot be reversed. Once an unstable atom has decayed, it becomes a more stable form and cannot revert back to its original state.
