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.

SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos. Our teachers and animators come together to make fun & easy-to-understand videos in Chemistry, Biology, Physics, Maths & ICT.

VISIT us at www.fuseschool.org, where all of our videos are carefully organised into topics and specific orders, and to see what else we have on offer. Comment, like and share with other learners. You can both ask and answer questions, and teachers will get back to you.

These videos can be used in a flipped classroom model or as a revision aid.
