Lothar Meyers Classification In The Form Of Curve
He arranged the elements in the order of their atomic weights they fall into groups in which similar chemical and physical properties are repeated at periodic intervals and in particular he showed that if the atomic weights are plotted as ordinates and the atomic volumes as abscissae the curve obtained presents a series of maxima and minima the most electro positive elements appearing at the peaks of the curve in the order of their atomic weights.
