1.	Chlorine has two isotopes, viz, Cl -35 and Cl-37. Their atomic masses are 35 and 37. Their chemical properties are same. Where should these be placed in Mendeleev's periodic table? In different places or in the same place?
Answer» Solution :Mendeleev arranged the elements in INCREASING order of ATOMIC mass. Since the atomic masses of the isotopes of CHLORINE are 35 and 37, they should be KEPT in different POSITIONS in the Mendeleev Periodic table.
