C. Increasing atomic masses
D. Decreasing atomic masses
Answer:C
According to Mendeleev’s periodic law, the elements were arranged in the periodic table in the order of:
A. Increasing atomic number B. Decreasing atomic number C. Increasing atomic masses D. Decreasing atomic masses
Explanation: Mendeleev’s periodic law is an arrangement of elements in increasing order of their atomic masses as Mendeleev’s periodic law states that, the physical and chemical properties of elements are a periodic function of their atomic masses.
