प्रश्न
What is the reason for the identical chemical properties of all the isotopes of an element ? Explain with the help of an example.
उत्तर
Many elements consist of a mixture of isotopes.The chemical properties of isotopes are similar. This is due to the fact that isotopes of an element have the same atomic number, which means that they have the same number of valence electrons.
Their physical properties are slightly different because the mass numbers of the isotopes are different.
For example- `""_17^35"Cl"` and `""_17^37"Cl"` show identical chemical properties as they have the same number of valence electrons (7).
