Question

According to the modern periodic law, the properties of elements are a periodic function of their:
A. Atomic volume
B. Atomic number
C. Atomic weight
D. Mass number

Answer 1

B. Atomic number

Explanation:

According to the modern periodic law, the properties of the elements are periodic function of their atomic numbers. The original law was known as the Mendeleev's Periodic Law. Because the properties repeated themselves regularly, or periodically, on his chart, the system became known as the periodic table. In devising his table, Mendeleev did not conform completely to the order of atomic mass. He swapped some elements around, which was then refined to given the periodic table that we use. The chemical and physical properties of the elements recur periodically when the elements are arranged in the order of their atomic weights.
