He didn't know about electron configuration.
The properties were repeated after 8 elements.
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.
look in your textbook. that is what it is there for. peace. LOL.

Dmitri Mendeleev was the first scientist to create a periodic table of the elements similar to the one we use today. This table showed that when the elements were ordered by increasing atomic weight, a pattern appeared where properties of the elements repeated periodically.
A table in which properties of elements are repeated after some interval.
periodic table
Because the elements that have similar properties are arranged in groups - or 'periods'.

If the elements are arranged in the order of their increasing atomic numbers, there properties are repeated in a periodic manner.
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.
