When did john newlands create his periodic table?
John Newlands first published his "Law of Octaves" in 1863. It pointed out a recurrence of properties for every eighth element in a scheme involving just 21 of between 55 and 60 elements known at the tiime. Two years later he presented to the Chemical Society in London a scheme that involved nearly all of the known elements. However he tried to 'force fit' elements into this scheme with little insight, and some of the family groupings are nonsensical. Mendeleev's Periodic Law was published in 1869. His first periodic table that went with it at the time was followed by a revised version in 1871 which incorporated all known element, and left gaps for elements yet to be discovered.
How did Moseley solve the problem of elements that did not fit the pattern according to their properties?
He rearranged the table, placing elements in order of atomic weight, not by property. This resulted in elements that had similar properties but were actually very unrelated from being placed incorrectly, and lead to them being put where it made more sense. After the reordering, they were also very much aligned by their properties, thus fixing the problem of those elements that didn't fit.
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.
How did mendeleev know that there were gaps in the the periodic table?
Dmitri Mendeleev noticed gaps in the periodic table when he arranged elements by increasing atomic mass and saw that certain elements with similar properties did not fit into the pattern. He predicted the existence and properties of these missing elements based on the trends in the known elements around them.
Are there more elements or non-elements?
There are more non-elements than elements. Non-elements refer to everything that is not classified as an element, such as compounds, mixtures, and substances that do not fit the definition of an element.
What did Johann Dobereiner and John Newlands find when they were trying to arrange the elements?
They both found patterns relating element properties to atomic weight, but when they tried to make them universal they broke down.Doebereiner's triads worked for some elements, but he was unable to fit every element into a triad. Newlands' first publication involved only about 25 of the more than 60 elements known at the time; when his work was criticized on this basis, he tried to "force fit" all of the other elements, arriving at some quite bizarre groupings.
How was mendeleyev able to predict the existence of elements that had not yet discovered?
Because there were gaps in the periodic table, which he invented. Unlike other scientist of the time who tried to make the elements fit theircategorising system, such as Newlands and his law of octaves, Mendeleev came to the conclusion that they had not discovered all the elements as he noticed patterns that allowed you to categorise elements if you left gaps that undiscovered elements could fill.

Limitations of newlands law of octaves?
This law could be best applied, only up to the element calcium. Also, newly discovered elemts could not fit into the octave structure and the feature of resemblance of the 8th element when arranged in increasing order of their atomic mass was not successful with heavier elements.
What do elements fit into?
