प्रश्न
Write scientific reason.
There was no definitive place for isotope in Mendeleev’s periodic table.
उत्तर
- Isotopes were discovered long time after Mendeleev developed the periodic table.
- Isotopes have same chemical properties but different atomic masses.
Therefore, there was no definitive place for isotope in Mendeleev’s periodic table.
