WebThe half-life of a substance is the time it takes for half of the substance to decay. ... Some atoms decay into other atoms that are also radioactive, so the remaining radioactivity depends on the type of atom. An example of a short half-life: the isotope, 260 Sg, has a half-life of approximately y 4 ms (or 4 thousandths of a second). WebGo each get to move at varying rates (fast, moderate and slow) to represent half-lives of different elements. Required example, radon has a half-life about 3.8 time, oxides possesses an half-life of 1600 years, and uranium has a half-life of 4.5 billion years. brynsworthy barnstapleWebThe half-life of a radioactive element is the time it takes before half of the atoms in a sample of the element have decayed. ...

"WebSo if you have one atom of an element with a half-life of 1 minute, you have a 50% chance that it decays within the first minute, 75% chance that it decays within two minutes, 87.5% within 3 minutes, and so on. You cannot predict when it will decay, but as numbers become close to 100 you know it eventually will. [deleted] • 6 yr. ago. " - Half life of an atom
