Question

(20) Write a short note on : Position of isotopes in the Mendeleev's and the modern periodic table.​

Answer 1

Answer:

AS ISOTOPES HAVE SAME ATOMIC NUMBER EVEN THOUGH DIFFERENT ATOMIC MASSES AND IN PERIODIC TABLE WE HAVE ARRANGED ELEMENTS ACCORDING TO INCREASING ATOMIC NUMBERS AND NOT ATOMIC MASSES SO ALL ISOTOPES ARE LOCATED IN THE SAME PLACE AS THE ELEMENTS. THERE IS NO SPECIAL PLACE IN THE PERIODIC TABLE FOR THE ISOTOPES.
