I am still not sure if he was aware of the concept but neglected to see the pattern, or if he just didnt have access to the information.

No he did not. Chemists then did not know about protons, neutrons, electrons, or nuclei. They were not even sure of atoms until 1861. He lived in the 19th century; chemists discovered these things only in the 20th. He ordered his table according to atomic weights, which could be found by laboratory work--making compounds and weighing them.

He probably wasn't aware of the atomic numbers (Mosley used this for organization) because he was working with atomic mass instead.

searching by some notes i got here across that Medeleev concept that if aspects were prepared by technique of the atomic mass, houses repeated themselves in commonplace kinds. This changed into customary as periodicity; houses of aspects are periodic applications of their atomic mass.

He worked with mass, not proton number aka atomic number

The answer is almost word for word in your Modern Chemistry book.
