Question

Would you place the two isotopes of chlorine Cl-35 and Cl-37 in different slots because of their different atomic masses or in the same slot because their chemical properties are the same?Justify
(regarding Mendeleev's periodic table)

Answer 1

Explanation:

different slot because regarding mandelliv periodic table it says that property of elements the periodic function of their atomic masses..... not atomic numbers (as given in modern periodic table)

Answer 2

In the periodic table of Mendeleev, both the isotopes of chlorine, i.e., Cl-35 and Cl-37 would be placed in different slots.

- Mendeleev's periodic table is based on the fact that the properties of elements are a periodic function of their atomic masses.

- Since Cl-35 and Cl-37 have different atomic masses, so they must be placed in different slots.

- But due to their similar chemical properties (as it is a more reliable property), they may also be placed in the same slot.
