Newland’s Law of Octaves and Dobereiner’s Triads laid the foundation for the development of the modern periodic table.
Think about the modern periodic table.
Modern periodic law states that the properties of elements are in periodic functions of their atomic numbers.
Every eighth element has similar properties when the elements are arranged in the increasing order of their atomic masses.
Groups of three elements (triads) could be formed in which all the elements shared similar physical and chemical properties.
Law of Triads states that the arithmetic mean of the atomic masses of the first and third element in a triad would be approximately equal to the atomic mass of the second element in that triad.
Remember the modern periodic law.
Properties of elements are the periodic function of their atomic masses.
The physical and chemical properties of the elements are periodic functions of their atomic numbers.
