not if u mean completely filled in but square by square yes
Main idea of mendeleevs first periodic table?
In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses and repeating periodic properties.
What were mendeleevs discoveries and predictions and discoveries abot the periodic table?
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.

Who is mendeleevs?
Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.
Why is the mendeleevs table called the periodic table?
Because the properties of the elements change in a periodic fashion. In the early versions, when fewer elements were known, the chemically similar elements were thought to occur every eight positions.
Why were Mendeleevs efforts on the peridic table more successfully the other scientist?
Mendeleev's table was more systematic. Elements were arranged in order of atomic masses.
