Mendeleev
Dmitri Mendeleev lived and worked in Russia
He developed his model of the periodic table in the 1860s, but published it in 1869
Mendeleev arranged the elements by their atomic masses and their properties

Mendeleev’s periodic table
Mendeleev left gaps in his periodic table to allow for elements that had not been identified, even predicting their properties

Modern Periodic Table
The modern periodic table arranges the elements in rows (periods) by their atomic numbers.
Elements having the same number of valence electrons, and similar properties, are in vertical groups or families.
