Question
All of the following are correct, except:
As the parent atoms of a radioactive element break down in a rock, they turn into daughter atoms.
Radiometric dating is a form of absolute dating that determines the actual age of the rock.
For each radioactive element, the time it takes to break down into daughter atoms is unknown.
Certain elements have different versions of themselves called isotopes.

The incorrect statement is:
"For each radioactive element, the time it takes to break down into daughter atoms is unknown."
Why: each radioactive isotope has a known decay rate (expressed as a half‑life—the time in which half of a sample decays). Radiometric dating depends on these known half‑lives (for example, C‑14 ≈ 5,730 years; U‑238 ≈ 4.47 billion years) to calculate ages.
