Question #f0ec1

Answer 1

Yes the chemical properties of isotopes are based on valance electrons there is no difference in chemical properties of isotopes.

Explanation:

For example Carbon 12 `C_6^12` the normal isotope of Carbon has the same chemical properties as Carbon 14 `C_6^14` .

Living things take in both Carbon 12 `C_6^12` and Carbon 14 `C_6^14`

The two isotopes of Carbon are used interchangeably in living things. Chemically they are the same.

The difference is that Carbon 14 `C_6^14` is radioactive and slowly changes to `N_7^14` . ( the half life is approximately 5,600 years)
The radioactive properties (not chemical properties) of Carbon 14 `C_6^14` are used to date how old a once living thing is.
