After one half-life, 50% of the atoms will reverse to a stable isotope and 50% will stay radioactive.

What do you mean by Half-life?

Half-life may be defined as the time required for the radioactivity of a specified isotope to drop to half its initial value.

After three half-lives, 87.5% of the atoms will reverse to a stable isotope and 12.5% will stay radioactive.

When the initial value of any compound is 100%, after one half-life, it will reduce to 50%, after the second half-life, it will reduce to 25%, after the third half-life, it will reduce to 12.5%, and goes on.

Therefore, it is well described above.
