Can there be an element with atomie mass 53 or 54 in between the two elements, chromium \(^{52}_{24}Cr\) and manganese \(^{55}_{25}Mn?\) |

Answer» In Mendeleev’s periodic table, the difference between atomic masses of two consecutive elements is not the same (52Cr and 55Mn). 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. \(^{52}_{24}Cr\rightarrow\,^{55}_{25}Mn\) that means in between two elements (Cr aind Mn), element with mass 53 or 54 do not exist. |
