Respuesta :
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.
