Mostly in increasing order of Atomic Mass. There were a couple cases where he swapped them so that the higher atomic mass came first; he made these decisions based on his knowledge of the chemical properties of the elements in question (he was pretty sure his hypothesis about them being periodic in their properties was correct, and when arranging them by mass interrupted that periodicity, he assumed the mass had been reported incorrectly).
We now know that they're periodic based on atomic number, not atomic mass, though the two are pretty correlated.

What is the important work of Dmitri Mendeleev?
Mendeleev was the inventor of the Periodic Table. He organized all the known elements into the periodic table based on atomic number. He was also able to predict the existence of elements that had not yet been discovered based on gaps in the table he created. Based on observations of other elements in the groups he was also able to predict the characteristics of these unknown elements as well. NICE! dude
What did Dmitri Mendeleev do during the Industrial Revolution?
Mendeleev laid the foundation for theperiodictable that we know today
What did Dmitri mendeleev invent?
The Periodic Table of Elements
When was the periodic table created and who by?
The periodic table was created by Dmitri Mendeleev in 1869. He organized the elements based on their chemical properties and their atomic weights, creating a system that arranged the elements into groups and periods. This arrangement allowed for the prediction of missing elements and became the basis for the modern periodic table.
What did Dmitri Mendeleev do?
dimitri mendeleev was the father of the periodic table of elements
Who was the chemist that organized the elements into a chart?
Dimitri Mendeleev
Who is Demetri Mendeleev?
He developed and organized the Periodic Table of Elements
What properties of elements did mendeleev list as he began to organize the elements?
Mendeleev arranged the elements in the increasing order of their atomic masses and repeating properties.
How are elements organized?
atomic number Chemical elements are organized in the form of the periodic table of Mendeleev, in groups and periods.
How did mendeleev organize the elements to create a periodic table?
He organized it according to the atomic mass.
What was Mendeleev's periodic table was organized by?
Mendeleev's periodic table was organized in order of increasing atomic masses. He arranged elements having similar properties together.
Who organized the elements into repeating groups of eight?
This was the Russian chemist Dmitri Mendeleev.
How did Mendeleev organize the elements to create the periodic table?
Mendeleev organized the elements according to their increasing atomic masses and considered their fundamental properties . He also considered the Hydrides and Oxides formed by the elements.
Mendeleev saw trends in the physical and chemical properties of elements when he organized them by .?
atomic weight
What information did mendeleev have about the elements he organized into the periodic table?
Because it has the atoms in the protons and neutrons
How is the current periodic table of the elements organized?
Mendeleev's version of the Periodic Table was organized by increasing mass. The modern periodic table is now organized by atomic number.
Why was Mendeleev's periodic table was useful?
Because it organized all of the existing elements and helped scientist discover more elements.
