Modern periodic law was put forward by Moseley, student of Roentgen. According to him "The properties of elements and their compounds are periodic functions of their increasing atomic numbers". He arranged elements in periodic table in increasing order of their atomic numbers. It was found successful due to number of reasons and the most important was the position of isotopes as they are nuclei with same atomic numbers so they were placed under the same elements to which they belong. This law also led to the discovery of many new elements. read less
