Dalton's new information on atomic weights allowed a Russian chemist, Dmitri Mendeleyev to create the Periodic Table of elements. This table provided the means for discovering new elements, and Dalton also proposed symbols for the elements.
No. The periodic table of the chemical elements is a tabular method of displaying the chemical elements. Although earlier precursors exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869. Heck yeah, he's my BFFL!! Although not specifically - He is credited with being the founder of the concept http://www.chemheritage.org/classroom/chemach/periodic/index.html
· Everything is made of atoms.
· Every atoms of a given element are identical, also with the same mass but have different masses from the atoms of other elements.
· A combination of two or more elements in a specific ratio of the atoms is a compound.
· Atoms can not be destroyed nor can they be created.
· In a chemical reaction, the reactants in atoms are rearranged to give the products of the reaction.
-the fourth one was later proved wrong. aka ww2 and the atomic bomb was created by spliting the atom apart.
In 1803, John Dalton published his list list of element. The list showed only five elements along with their atomic weights. The elements were hydrogen, oxygen, azote (now nitrogen), carbon and sulphur.
Dalton's second list of 36 elements came out in 1827 and contained elements: oxygen, hydrogen, azote (now nitrogen), carbon, sulphur, phosphorus, Mercury, copper, iron, nickel, tin, lead, arsenic, lime (now calcium), manganese, uranium, tungsten, titanium, calcium, magnesia (now magnesium), barytes (now barium), strontium, aluminium and silicon

Mendeleev was working in St Petersburg in Russia when he first published a periodic table. He never referred to a "periodic table", but always to the "periodic law", because it was his insight and mission to proclaim the periodic classification as expressing a law of nature rather than a mere convenient arrangement of elements.
Mendalev created the periodic table, and arraged it by atomic mass, but then Dalton came, and arranged it by atomic #

yes
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.
Dimitri Mendeleev produced the first periodic table leaving spaces for elements that were not yet known in 1869; Henry Mosely determined the atomic number of elements and corrected some inaccuracies in Mendeleev's periodic table.
John Dalton is best known for work on atomic theory. While his models were very similar to the speculation of the Greeks made centuries before, his theory differentiated in the idea that chemical combination takes place between particles of different weights.
1) elements are composed of atoms 2) atoms of same elements = 3) atoms of different elements not = 4) atoms fomr compounds in definite ratios H2O
Dmitri Mendeleev published the first periodic table in 1869. He built on the work of several other scientists, including Antoine Lavoisier, Johann Dobereiner, Alexandre-Emile Beguyer de Chancourtois, and John Newlands, who had previously studied the best way to classify the elements.
No, Dmitri Mendeleev in Russia developed the first periodic table.

John Dalton is largely credited with the development of atomic theory, in addition to coming up with the concepts on which the modern periodic table would be founded upon. His atomic theory revolved around the notion that the atoms of different elements differ in weight--and thus may be distinguished by their weights.
He called it the periodic table.
dalton wasnt the one who experimented with gold, rutherford was the one who did the gold foil experiment.
john Dalton died in 1854. The first periodic table was published in 1869. But john Dalton did put forward the first clear idea of atoms and molecules.
August 20, 1864 was when John Alexander Reina Newlands produced the first periodic table of the elements.
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.
John Dalton introduced the basic concepts on which the modern periodic table is based.
what is john daltons scientific attitude
A variety of people are claimed to have helped create the periodic table including Kekule and John Newlands, but the credit to how the Periodic Table currently looks (some gaps filled in by other chemists) typically goes to Mendeleev.
