How thd the position of \(^{35}_{17}Cl \) get fixed in the modern periodic table? |
|
Answer» In Mendeleev’s periodic table, the difference between atomic masses of two consecutive elements is not the same 35Cl and 35Cl. Moseley found out the atomic number of the elements. The atomic number of any element is increased by one unit (number) from the atomic number of subsequent element. Isotopes \(^{35}_{17}Cl\) and \(^{37}_{17}Cl\) occupy the same position in the modern periodic table. Both isotopes have the same atomic number. In the modern periodic table, the elements are arranged in the order of their increasing atomic numbers, that the problem of discrepancy in the pairs of isotopes elements observed in Mendeleev’s periodic table was solved. The isotopes of \(^{35}_{17}Cl\) and \(^{37}_{17}Cl\) were placed in the same group as both have the same atomic number. |
