Question
Write the contribution of Lothar-Meyer in classification of elements.
✓

Answer

Lothar-Meyer made graphs between the physical properties of elements, such as atomic volume, melting point, boiling point and atomic weight and found that elements with similar properties are at the same position. Hence they show similarity among the elements of a certain group, they are called Lothar-Meyer's Curve. They helped in classification of elements.
