∙ 9y agoWhen three-quarters of a radioactive isotope has decayed, it means that 1/4 (or 25%) of the original isotope remains. This corresponds to 2 half-lives, because each half-life halves the amount of radioactive material remaining.
Parent and daughter isotopes occur in radioactive decay processes. The parent isotope is the original unstable isotope that undergoes radioactive decay to form the daughter isotope. The daughter isotope is the stable isotopes produced as a result of the decay of the parent isotope.
When the element is stable. (apex)
No. Some only last a tiny fraction of a second, some last hundreds of thousands of years.
If I take a radioactive sample of 400 moles of an unknown substance and let it decay to the point of three half-lives I would have 50 moles left of the sample. 1/2 of what is left will decay in the next half-life. At the end of that half-life I will have 25 moles left of the unknown substance or 4/25.
3 half-lives

Adopting a daughter is always a good option. It brings a daughter into your life as well as brightening their lives.

1/8 = (1/2)3 which is in the form (1/2)n where n is the number of half lives undergone. Therefore the substance has passed three half lives
