Mendeleev used the analogy of playing the card game of solitaire to help him organize the known elements into a Periodic Table. The suits of the cards were analogous to the groups of the elements and the numeric values of the cards were analogous to the values of atomic weights.

Who arranged the periodic table according to increase in atomic weights?
Dmitri Mendeleev, a Russian scientist. He arranged cards in atomic weight order and noticed patterns (periods). This resulted in him being able to guess which elements were missing and complete the periodic table.
The chemical properties of matter comes mostly from?
The chemical properties of matter are mainly determined by the electrons in the outermost orbital shell. The exceptions to this occur in e.g. the Lanthanides and the Actinides, where as a group, the outermost shell of each is equally filled, and it is the number of electrons in the next innermost shell that now comes into play. Hence their very similar chemistry.Similar considerations apply to both the columns and the rows of the periodic table, where those the elements share somewhat similar properties.Mendeleev, by arranging a set of cards, each representing one element and its properties, was able to arrange the cards to form his periodic table, and thus predict where new elements could be found. His predictions also pointed to where elements had been incorrectly placed.
What information did Mendeleyev write about each elements on his cards?
He wrote information that is found on the periodic table: the atomic number, the element, the mass number and etc.

The discovery of a periodic table closest to its modern form was the result of which scientist's work with decks of cards?
Dmitri MendeleevDmitri MendeleevDmitri Mendeleev is the scientists that worked with decks of cards to decelop the arrangement of elements on the periodic table in the 1860's.

What did Mendeleev write down on note cards while he was observing different elements?
Density, color, and automatic Mass

How did Mendeleev arrange the chemical elements in the periodic table?
Mendeleev arranged the elements by their relative atomic mass. Each one of his rows began with an element that had 1 valency and ended it with inert gas elements. The creator of the Periodic Table, Dimitri Mendeleev, arranged the elements by atomic number (amount of electrons) and amount of electron shells. This then lead to columns (groups) of elements with the same amount of electrons in their outer shell. So, now, every period contains elements with ascending atomic numbers. Every group contains elements with ascending amounts of electron shells.

How was mendeleyev able to predict the existence of elements that had not yet been discoved?
Dimitri Mendeleev created a set of cards with information about each element on them. He aligned these cards in order of increasing Atomic Mass and found that after so many elements, a specific trait would appear in each. For example, Lithium and Sodium both react violently with water. Mendeleev then filled in (predicted) what would go in the empty spaces based on the elements that would share similar properties, based on the patterns he had already seen. Mendeleyev (alternate spelling) in 1800 put all the known elements on cards and set them together according to their similarities. He saw an inconsistency in the organization because titanium was not related to aluminum and boron. He moved one over to another row, where it fit perfectly, but there was a gap in the middle of the table. He predicted one element would take its place, and predicted 30 more elements.
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.
