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.
