How can a half-life be used to tell the age of a sample?
Question 1 options:
The ratio between the radioactive form and the stable form depends on the archaeological record.
The half-life of an isotope is constant.

Explanation / Answer
Option B) The Half-life of an Isotope is Constant.
By Finding the Amount of the sample in stable form and radioactive form, one can find the age of the sample using Half- life, which is defined as the amount of time it takes for one half of the radio-active substance to decay into stable form.
