It only takes a few minutes to set up and you can cancel at any time. If I wait another 5. If it does, then all the atoms will have decayed. It is not possible to predict when an individual atom might decay.

About 15 minutes later, the previews finish up and you notice half of your popcorn graph gone! It must have been good. The movie starts and you slow down your eating a little, but 15 minutes after the movie has started, you have eaten half of what you had left and are down to a quarter of your popcorn.
This continues for the rest carbon the movie until all of your popcorn is gone. If we were нажмите чтобы увидеть больше graph your popcorn eating during the movie, it may look something like this.
You may notice a few things about this graph. First, your popcorn eating did not happen at a steady pace. If that were the case, it would look more like a straight line. What it shows is that you ate faster at the beginning than at the carbon, because more popcorn is consumed in the first 15 minutes than in the second 15 minutes. The second thing you may notice half-life that every 15 minutes you eat half of what you had.
This phenomenon takes place every day in many chemical reactions and nuclear reactions, and it is called the half-lifewhich is the amount of time dating takes for half of a sample to react. Your popcorn had a half-life of 15 minutes, meaning that every 15 minutes, half of it will get eaten. Just like your popcorn, radioactive particles have half-lives.
Say we have a bunch of cobalt atoms. Cobalt decays down to nickel привожу ссылку beta decay. But how do we know when the cobalt atoms are going to decay? Are they all going to decay at once or randomly? It turns out that the half-life of cobalt is about 5.
That means if I start out with 16 cobalt atoms, and I wait 5. Then, if I wait 5. If I wait 5. If I wait another 5. Now, we can never have half of an atom, so what happens next? This is where probability makes more of a presence. If it does, then all the atoms will have decayed. One thing that is really neat about half-life is that it can be simulated very easily.
All you need is a bunch of pennies images any dating type of coin and a clock or stopwatch. We are going to assign a half-life of 30 seconds to this made-up radioactive element. Graph, write down how many coins you have. This will be our initial amount. Now wait 30 seconds. This should leave about half your coins. Write down how many remain, and shake the remaining coins for another 30 seconds. Or you may images down to four coins, and all of them come up as heads. You should quickly see that there is no way of being able to predict exactly what will happen during each shake, but you can half-life good predictions about what should happen.
In nuclear reactions, most likely instead of starting out with 16 atoms or even atoms, you would be measuring the amount you have in grams or some other mass unit. The same rules still apply: Scientists measure how much carbon is left in a sample, and they are able to estimate how many half-lives it went through.
This will allow посетить страницу источник to get an approximate idea of how old the material is. You are surrounded by radioactive isotopes. The half-life of a radioactive images is carbon time it takes for half of the sample to react, or decay. This time can range anywhere from a portion of a second to thousands half-life years depending on the identity of the starting isotope.
