In 1869, Mendeleev organized his Periodic Table by increasing Atomic Mass (atomic weight), using what is called the "law of octaves," by which every 8th element in the sequence shared similar properties. This was first observed by John Newlands in his element table around 1863.

What periodic trends did did Mendeleev organize his periodic table by?
Atomic Mass Octaves and Triads
Who preceded Mendeleev and Meyer with work on the periodic table?
Newlands and Dobereiner. Newlands did the Law of Octaves. Dobereiner did the Triads.
The scientist involved in the periodic table?
John newlands attempted to arrange the elements into the law of octaves but had got mocked by many peers
What are the similarities between the Law of Octaves and the Periodic Table?
The properties of elements in the periodic table are repeated at intervals of eight atomic numbers.Unfortunately, in music word "octave" refers to the scale between the first and eighth note - second note is seven notes after the first. In the periodic table, the pattern repeats after a gap of eight elements.
How many groups did newlands periodic table have?
Newland arranged all the then known elements into seven groups in his 'law of octaves'
What periodic trends did did Mendeleev organize his periodic table by?
Atomic Mass Octaves and Triads
What periodic trends did Mendeleev organize his periodic table by?
atomic mass, triads, and octaves
Who preceded Mendeleev and Meyer with work on the periodic table?
Newlands and Dobereiner. Newlands did the Law of Octaves. Dobereiner did the Triads.
Was there been more than one periodic table?
Before the modern periodic table , the concepts for classification of elements were given by Dobereiner , Newland law of octaves ,Mendeleev's periodic table.
Why was Newlands and periodic table rejected?
John Newlands, in designing his table, believe that it was governed by the "Law of Octaves". While this is true for elements in what are now groups 2 and 3, it fails in period 4, when the periodicity becomes 18.

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.

Newland arranged all the then known elements into seven groups in his 'law of octaves'
Who is credited for discovering the periodic table?
Dmitri Mendeleev 1834-1907 however, Antoine Lavoisier in 1790's had compiled a list of elements (so basically the 'first periodic table') Than in 1864 John newlands "proposed an organized scheme for elements." He created the law of octaves. when he noticed that "when elements were arranged in increasing atomic mass their properties repeated every eighth element.' (first and eighth elements had similar properties). However 1869, Lothar Meyer 1830-1895, AS WELL AS Dmitri mendeleev 'demonstrated connection between atomic mass and elemental properties'. HOWEVER: "Mendeleeve is given more credit because he published his orgnanization scheme first and better demonstrated its usefulness." Quotes from my text book p 151 (glencoe science: chemistry matter and change)
How is the modern periodic table different from the first periodic table?
when the periodic table was first made, it only had the basic elements eg. hydrogen, oxygen, etc. Now with scientist finding more elements and creating them eg. americum, einstienium or europium, there are more elements than ever before. An element only has to exist for 2 seconds before they put it on the periodic table.
How octaves does a bassoon have?
A bassoon can play 4 octaves.
