Mendeleev's table was arranged by Atomic Mass and the periodic table is arranged by protons (atomic number).
it has elements
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.

In chemistry, none! the period table does not exist one can only find the periodic table although the rows of the periodic table are called periods or series. !
He left too many spaces between the elements......

To understand the concept of Periodic Table
Mendeleev's periodic table of elements certainly wasn't created in 1901
In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses and repeating periodic properties.

Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.

The difference between a period and a group is that:A periodic is a horizontal row of elements in the periodic table, which simply means the column of the periodic table.A group is a vertical row of elements in the periodic table, which simply means the row of the periodic table.
