The properties were repeated after 8 elements.
Dmitri Mendeleev, who created the first periodic table, did not understand why the properties of elements repeated because he did not know about atomic structure and the concept of atomic number. It was later discovered that the repetition of properties was a result of the elements being arranged in order of increasing atomic number, leading to the modern periodic table.
he arranged the various in the increasing order of atomic mass and found that some properties of the elements were repeated at certain intervals of atomic masses
The properties of elements are periodic function of their atomic number. The properties are repeated after certain interval.
Dmitri Mendeleev concluded that when elements are arranged in order of increasing atomic mass, their properties repeat periodically. He left gaps for undiscovered elements and predicted the properties of these missing elements based on their neighboring elements. This led to the development of the modern periodic table.
The properties were repeated after 8 elements.
If the elements (which were discovered by his time) were organized in the increasing order of their atomic weight, they will exhibit an apparent periodicity of properties. It also had the ability to predict physical and chemical properties of some undiscovered elements.

periodic table
A table in which properties of elements are repeated after some interval.
Dmitri Mendeleev, a Russian scientist, is credited with creating the periodic table of elements in the 19th century. He arranged the elements in order of increasing atomic mass and grouped them based on their chemical properties, leading to the development of the modern periodic table.
he arranged the various in the increasing order of atomic mass and found that some properties of the elements were repeated at certain intervals of atomic masses
Because the elements that have similar properties are arranged in groups - or 'periods'.

The properties of elements are periodic function of their atomic number. The properties are repeated after certain interval.
If the elements are arranged in the order of their increasing atomic numbers, there properties are repeated in a periodic manner.
