HALF LIFE OF RADIOACTIVE ISOTOPES ANSWERS
Half Life of radioactive isotopes
slideplayerImage: slideplayerThe half-life of a radioactive isotope is the time it takes for half of the atoms in a pure sample of the isotope to decay into another element. It is a measure of the stability of an isotope; the shorter the half life,the less stable the atom.

Half-life is defined as the time period that must elapse in order to halve the initial number of radioactive atoms. of dozens of elements,with half-lifes from fractions of a second to millions of years.Half-life | radioactivity | BritannicaSee all results for this questionHow is the half life of an isotope determined?How is the half life of an isotope determined?An element's radioactive decay can be determined through a single equation which requires imputing the isotope's half life,its rate of decay and the decay time since the rate of decay is measured. Every isotope has its own half-life. The half-life is the amount of time it takes for a given quantity of the isotope to lose half of its radioactivity.How do you calculate radioactive decay? | ReferenceSee all results for this questionWhat is half life of radioactive iodine?What is half life of radioactive iodine?The half life of Iodine-131 is about 692,988 secondsSee all results for this questionHow are stable and radioactive isotopes different?How are stable and radioactive isotopes different?Stable isotopes are different forms of the same chemical element,having stable nuclei. Radioisotopesare unstable isotopes of chemical elements that undergo radioactive decay. Stability. Stable isotopes are very stable and do not undergo radioactive decay. Radioisotopes are very unstable and undergo radioactive decay to obtain a stable state.Reference: wwwerencebetween/difference-between-stable-isotopes-and-vSee all results for this question

What is the half-life of a radioactive isotope - answers
Radioactive isotopes decay from their parent isotope to daughter isotope at a constant rate (under any circumstances). The rate at which a parent isotope decays to its daughter isotope is considered one half life. Carbon-14 has a half life of 5730 years and its daughter isotope is Nitrogen-14.

Which radioactive isotopes has the shortest half life
A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay. For example, if the half-life of a 50.0 gram sample is 3 years, then in 3 years only 25 grams would remain. During the next 3 years, 12.5 grams would remain and so on.4/5(1)
Half life of Radioactive Isotopes - Chemistry Mr Nguyen
Half life of Radioactive Isotopes - Chemistry Mr Nguyen.. Final mass = 100.0 g x (1/2) 3 , which gives us 12.5 grams. A 50.0 g sample of N-16 decays to 12.5 g in 14.4 seconds. What is its half-life? Ans: 7.2 seconds Answer was discussed in class. The half-life of K-42 is 12.4 hours.Author: Cinnamonspider
What is the half life of radioactive isotope - answers
The half-life of a radioactive isotope is defined as the time taken for the isotope to decay to half of its initial mass. So to decay to 50 percent of its initial mass will take one half-life of the isotope. One half-life of the isotope is 10 hours so the time taken to decay is also 10 hours.
Half-life of Radioactive Isotopes? | Yahoo Answers
Oct 20, 2007Looking at this then, we can determine that 12.5 g is half of 25.0 g. If it decayed to 12 in 14.4 s, then we can deduce that it decayed to 25g in 7.2 seconds. The more time that elapses the more of the substance decays, which is why the answer wasn't 28.8. At 28, there would be even less remaining, until it was eventually all gone.Status: OpenAnswers: 1[PDF]
Half Life of Radioactive Isotopes Name: Date: 1. Carbon -14 is a radioactive isotope found in small amounts in all living things. When the living thing dies, the carbon -14 begins to decay at a steady rate with a half -life of 5,730 years; meaning that for every 5,730 years that passes, exactly half of the original amount of carbon -14 has decayed. Scientists are able to measure the amount of carbon -14 left in a
