Why octave\'s law of triad discarded ??? |
| Answer» \xa0Newland’s law of Octaves explains when elements are arranged by increasing atomic mass, the properties of every eighth element starting from any element are a repetition of the properties of the starting element.\xa0It was discarded because:1. This classification did not work with heavier elements,i.e. those lying beyond calcium.2. Newland adjusted two elements cobalt and nickel in the same slot and these were placed in the same column as flourine , chlorine, and bromine which have different properties than these elements.3. Iron, which resembles cobalt and nickel in properties has been placed far away from these elements. | |
