MENDELEEV'S PERIODIC LAW:
He studied the chemical propeties of all 63 elements known at that time . on the basis of their prperties , he proposed that when elements are arranged in the increasing order of their atomic masses , the elements with similar properties appear at regular intervals of periods , i.e. , chemical properties of the elements are a periodic function of their atomic massaes (atomic weights).
Mendeleev (1871) arranged all the known 63 elements in the increasing order of their atomic masses . The arrangement of elements was made in horizontal rows (called periods) and vertical columns (called periods) .
