How did mendeleev decide how to arrange his cards of elements?
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.
When did the periodic table start getting used?
The periodic table of elements was first created by Dimitri Mendeleev in 1869. However, it took several years for his version to gain widespread acceptance and use. Since then, the periodic table has become an essential tool in chemistry and has undergone many revisions and refinements.
Why was the development of the periodic table important?
It is easier to study the properties of elements, if they are arranged in a proper way as in the periodic table. Elements in a given group have same number of valence electrons and hence generally have similar properties.
What is the name of the scientist who first developed the periodic table?
You can mainly blame the Russian chemist Dmitri Mendeleyev (or Mendeleev, or Mendeleyef - there are many different spellings of his name.)Back in the early 19th century, a German chemist named Johann Dobereiner noticed that some of the elements fitted naturally into groups of three, called triads, with similar chemical and physical properties. The English chemist John Newlands was the first to notice that if you arranged the elements in order of atomic mass, they seemed to have similar physical and chemical properties every eight elements. He called this the law of octaves, because the way in which these properties repeated every eight elements was similar to the way the same note was repeated every eight notes (octave) on a piano. However, at times his scheme broke down, and he realised there was something wrong with it, abandoning the octave idea. His fellow chemists mocked him for it - someone once said he'd have better luck listing the elements in alphabetical order and looking for patterns!It was Mendeleyev who in 1859 took Newlands' idea of looking for repeated properuties in the elements, and decided to create a table of elements in increasing atomic mass. Unlike Newlands, he left gaps where the pattern did not fit, and predicted new elements would be discovered, predicting their properties from the table. These elements were subsequently discovered, and since then, Mendeleyev's periodic table has been the most useful chart in chemistry.
Why is periodicity an important concept?
Periodicity reflects the properties of elements and represents similar electron configurations. Just took the test and got a 100% :)

What step did farmers take to organize themselves?
The steps the farmers took to organize themselves was that they got together and they got into groups called progressives
Who descovered periodic table of elements?
A lot of people noticed similar trends, but it took Dmitri Mendeleev to organise them by increasing atomic number and group them by similar characteristics.
Who put the periodic table in order?
It took many years to discover these elements. Hundreds of thousands worked and arranged the Periodic Table of Elements.The basic design of the periodic table was thought up by Dmitri Mendeleev. It was his idea to arrange the elements according to atomic mass (because this gave repeating patterns of properties). Later it was discovered that atomic charge was what was really important. Eventually the gaps Mendeleev left were filled in by the discovery of more elements, so while many scientist contributed to the modern periodic table Mendeleev is considered to have invented it.

Who first thought of the periodic table?
Many people thought of the idea, but we have given credit to Dmitri Mendeleev in 1869. I think its because he took the idea further and inscribed detail into his table, even predicting future elements. However, Lothar Meyer has also produced a similar version at essentially the same time as Dmitri Mendeleev.Some precursors include:Johann DobereinerA.E.Beguyer de ChancourtoisJohn Newlands
What were the results of the steps the they took?
It depends on who "they" were.
