The properties were repeated after 8 elements.
every two elements
Usually after 8 elements.
7 elements
He left too many spaces between the elements......
When Mendeleev made the table, he found that elements with similar chemical properties formed groups. This is because the pattern of the table reflects the pattern of filling the electron shells. Mendeleev didn't know this, and his achievement is all the greater because he had only his knowledge of the way elements behave to guide him.
Mendeleev created his periodic table at the time when presence of sub-atomic particles like electrons, protons and neutrons were not discovered.So, the term atomic number was not known till now. So , he positioned the elements in increasing order of atomic mass because atomic mass of many elements discovered till then were known.
that many of the physical and chemical properties of the elements tend to recur in a systematic manner with increasing atomic number.
the samepattern for how many protons all elements have to they are all factors of each other. That is why the periodic table is set up the way it is in that awkward shape
He left too many spaces between the elements......
It is pretty old fasioned. It was used to refer to a set with infinitely many elements or with repeated elements (or both).

A repeated rhythm is when a specific pattern of beats or notes is played consistently throughout a musical piece. It helps create structure and drive in the music, providing a foundation for the melody and other musical elements to build upon.

in india it is repeated after every 10 years
