2.
diagnose kidney function
3.
date geological formations
4.
date once-living things

Respuesta :

Answer:3)date geological formations

Explanation:

The ratio of the mass of U-238 to the mass of Pb-206 can be used to date geological formations.

Use of radioactive elements

Radioactive elements have unstable nucleus and they can be used for dating.

Examples of radioactive elements

  • Uranium 238
  • Lead 206

The ratio of the amounts of U 238 and Pb 206 in a rock sample enables the age of the rock to be estimated using the technique of radiometric dating.

Thus, the ratio of the mass of U-238 to the mass of Pb-206 can be used to date geological formations.
