(b) Name the scientist who first of all showed that atomic number of an element is a more fundamental property than its atomic mass. (c) State Modern periodic law. WebAccording to Dobereiner’s laws of triads, when some elements of chemical groups form in order to increase atomic masses, triads or groups of three elements have similar chemical properties to obtain. The atomic mass of the middle element of the triads can be equal to the arithmetic mean of the atomic masses of the other two elements. taichung bus schedule
