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
yes
Mendeleev noticed that a pattern of properties appeared when he arranged the elements in the order of increasing atomic mass.He found that the properties repeated regulary,
He had to sing a song about the elements!
It is The Periodic Table of Elements
mendeleev arranged elements according to atomic mass. He was able to observe periodicity when arranged in this pattern.
The properties were repeated after 8 elements.

Because he was creating a book called the Principle of Chemistry and he noticed the pattern in every elment. So he made a table or (chart) called Periodic Table of Elements.
A Pattern of properties appeared when he arranged the elements in order of increasing Atomic Mass
Mendeleev arranged the elements are arranged in order of increasing atomic masses. He founded that properties of elements are periodic when arranged in this pattern.

He did order it in the periodic table, but i think what your looking for is that he arranged it in order of increasing Atomic mass
The properties were repeated after 8 elements.
Demitri Mendeleev discovered a pattern to the periodic table in 1869.
I believed you are referring to Dmitri Mendeleev. He left blank space because he was able to deduce a pattern between the chemical properties of the elements an their atomic weights. He also noticed gaps in this pattern and hypothesized correctly that these blank spots corresponded to elements that had not yet been discovered.
Dmitri Mendeleev arranged the elements in periodic table according to increasing weight. He found their properties to be periodic when arranged in this pattern.
