Mendeleev’s periodic law states that the properties of elements are a periodic function of their;
A
atomic volume
B
atomic size.
C
atomic mass.
D
atomic number.
Explanation
Mendeleev prepared the periodic table based on the atomic mass. Elements in the periodic table are arranged in the increasing order of their atomic masses. Elements with similar physical and chemical properties are repeated after some steady interval in the periodic table. Hence, according to Mendeleev’s periodic law the properties of elements are a periodic function of their atomic mass.
