There should be a sufficient amount of the selected isotope in the rock.
The half-life of the isotope must be long enough to capture the age of the rock.
Explanation:
Sully must consider two main aspect before selecting her choice isotope for dating.
There must be sufficient amount of the selected isotope in the rock.
The half - life of the isotope must be long enough to capture the age of the rock.
- Radiometric dating gives a rock an absolute numerical age.
- The half-life of an isotope is time take for half of a radioactive element to decay.
- If the half-life of an isotope is very short, all the parent nuclide would have turned to daughter nuclides.
- Also, we must have sufficient amount of both the daughter and parent isotope in the selected rock.

<span>The correct answer is neither attraction nor repulsion.</span>
<span>Kinetic Molecular Theory explains that gas particles are in constant motion and exhibit perfectly elastic collisions. The motion of gas particles is random, meaning that there are no attractive forces on each other or on their surroundings. When two particles collide, the total kinetic energy is conserved.</span>
