"When elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties" is a statement of the periodic law.
Periodic means repetition. Properties of elements are found to be periodic when arranged in order of atomic number.
That there is a periodic repetition of their physical and chemical properties. #RRS
Periodic Law
According to the Modern Periodic Law, the properties of the elements are repeated after certain regular intervals when these elements are arranged in order of their increasing atomic numbers. Further an examination of the electronic configuration of the various elements clearly indicates that with a gradual increase in atomic number there occurs a repetition of similar outer electronic configurations after certain regular intervals. By correlating these two observations, we can say that, the cause of periodicity in properties is the repetition of similar outer electronic configurations at certain regular intervals. When we go across the period the no. of shells remains same but the number of electrons keep increasing .this result in more force of attraction among electrons and protons and thus atomic size decreases. But when we go down the group, the no. of valence electrons remains same but the no. of shells keep increasing.this result in less force of attraction. Therefore, atomic size increases.
The repeating pattern of elements of their properties is called periodicity. Elements are arranged according to same chemical properties.
No. When the elements are arranged in order of increasing atomic number there is a periodic repetition of their physical and chemical properties.

The periodic law states that when the elements are arranged by increasing atomic number, there will be periodic repetition.
Mendeleev's table was also based upon his Periodic Law, which stated that when elements are arranged by increasing atomic number, there is a periodic repetition of similar chemical and physical properties.

No. The modern periodic table is arranged in accordance to increasing atomic number and repeating properties.
Mendeleev arranged his version of the Periodic Table in terms of ascending atomic weights and similar properties. Since it was first published in 1869, there have been updates and improvements.
The elements are arranged in the increasing order of their atomic number and repeating properties.
The elements are arranged in the increasing order of their atomic number and repeating properties.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
