He used an Atomic Mass, and also an atomic mass of units. Therefore he was able to find the pattern. I got this answer off of Mr. Kebblers class.

What did Dmitri Mendeleev find when he organized the elements by mass?
I believe the correct answer is he was able to predict the existence of yet undiscovered elements, due to the gaps. For instance, I believe germanium was one of the elements undiscovered in the table, its placeholder was called ekasilicon.
Why did Dmitri make the periodic table?
Dmitri Mendeleev arranged the elements known at that time in the increasing order of atomic masses and repeating properties, so that it is easier to classify and study the properties of the elements.
How many elements were on the first Periodic Table?
The initial development of the Periodic Table was attriibuted to Russian scientist, Dmitri Mendeleev.The first Periodic Table was published by Mendeleev in1869 and comprised 63 elements, arranged by their atomic masses and according to the increasing number of protons in their nucleus.
What inspired Mendeleev to create his organization for the elements?
Mendeleev, a Russian chemist, organized the periodic table in order of relative atomic mass. He realized that the physical and chemical properties of chemicals were related to their atomic mass, and arranged them in a way so that groups of elements with similar properties fell into vertical columns (groups) with each period's elements having incrementally greater mass than the masses of the elements in the periods above it.According to Mendeleev, he had a dream about the elements falling into place on a table. His work was partly based on the work of Anton Lavoisier, who discovered the role of oxygenin combustion, and gave the element its modern name.
What was mendeleev's dream?
The story goes.... In the search for the relationship between the known elements, Dmetri Mendeleev's devised a card game made of elements; sort of like 'elemental solitaire'. In this game, each card had one element written on it with its atomic weight. He spent 2 sleepless days attempting to find a relationship by grouping the cards together on the table. On the third day there was a snow storm and Mendeleev's decided to stay home. Although restless he eventually fell asleep in which he dreamed a scientific breakthrough. In this dream he saw the elements arranged in a table and they were grouped together by various properties. When he awoke, he attempted to group the known elements in this manner and noticed that in order for this arrangement to work, he needed to leave spaces or gaps for other elements. Therefore, he also discovered that there were many other elements needed to be discovered.
Which arrangement of elements did Mendeleev find produce a repeating pattern of properties?
Increasing Atomic Mass
Which arrangement of the elements did Mendeleev find produced a repeating pattern of properties?
Increasing atomic mass
What pattern did Mendeleev find while organizing information on the elements Answer NOW?
Mendeleev was the scientist who first devised the periodic table of the elements. The pattern he found was that elements have periodic, or repeating series of properties. If you write down the elements in a series according to increasing atomic number, there is a repeating pattern; first metals, then nonmetals, then noble gases, then back to metals. This pattern helps us to understand why elements have the particular chemical properties that they have. It is fundamental to the science of chemistry.

What did dimetri mendeleev find out about the periodic table?
Mendeleev arranged the elements in a table ordered by atomic mass, corresponding to relative molar mass as defined today.

I believe the correct answer is he was able to predict the existence of yet undiscovered elements, due to the gaps. For instance, I believe germanium was one of the elements undiscovered in the table, its placeholder was called ekasilicon.
Why did Dmitri make the periodic table?
Dmitri Mendeleev arranged the elements known at that time in the increasing order of atomic masses and repeating properties, so that it is easier to classify and study the properties of the elements.
What 109 things of the periodic table will you find?
Yes, all the elements (natural or artificial) are contained in the periodic (Mendeleev) table of the elements.
What are the limitations of Mendeleev?
At first, he couldn't find a specific place for hydrogen, and the inner transition elements were not placed correctly.
Why did mendeleev leave gaps in the table?
Scientists suggest Mendeleev left gaps in the periodic table because Mendeleev knew the elements existed; however, was unable to prove it.
What year did Dmitri Mendeleev create the periodic table?
Dmitri Mendeleev created the periodic table in 1869, which organized the known elements based on their atomic properties and characteristics. Mendeleev's periodic table played a significant role in predicting the properties of undiscovered elements and has been the foundation of the modern periodic table.
Which elements did Mendeleev leave spaces?
What Mendeleyev did with the empty spaces was that he left them empty. Say for example, he didn't know Boron, because it wasn't discovered at that time. He left the spot for Boron empty because he didn't know what it was. He predicted that in the future, scientists would find out about new elements, and his predictions were right. That's why, the modern Periodic Table of Elements has more elements that Mendeleyev had put on his list of elements.
