Half life | Radioactivity | Physics | FuseSchool
This atom has an unstable nucleus. Any moment now it may undergo radioactive decay. Any time now... Or it may not! We just don’t know, as decay is a random event. We cannot predict when any single nucleus will decay. But we can say, if we have a large enough number of atoms, then decay will happen somewhere in a sample. If we time how long it takes for half of the atoms to undergo decay we have a measure, half-life, of a rate of decay.

there are 3 dashes in the title of this video. HALF LIFE 3 CONFIRMED
Bro i was lookint for half life 3
What is meant by the initial amount of C-14, how do we measure the initial amount in comparison to what is left at the moment?
About that beer I owed ya!
pls three version half life 3 confirmed
Great job! Keep up the good work, also this is the first vid on ur channel that I watched.

:25 what was that? We can't predict.... then continues on explaining that we can? How do you test with certainty, the half life of anything if its only good for 55,000 years? Just asking. Looking for answers.

Although you cannot predict when one particular atom will decay you can say, with certainty, the chance it will decay. The half life of an isotope tells you that half the atoms will have decayed in that time. Now consider the 50% which are left - in the next half life 50% of them will have decayed, leaving only a quarter of the original isotope after 2 half lives. To say the decay is random maybe gives the wrong impression. You can say, with certainty, that each atom, in a substance with half-life of 55,000 years has a 50% chance of decaying during those 55,000 years, but which of the atoms actually does decay is random!

Can we say that randomness, is random to us just because we have not figured out a rule for it?

Why is it called "half-life" not a full life? I don't get it :(

Half-life means the period of time required for one half of the atomic nuclei of a radioactive sample to decay.
