∙ 12y agoMr. John DaltonB..1766D..18441803 john put it together.teacher and scientist about 4 yrs later Daltonwrote a book called" A New System of Chemical Philosophy.Me personaly hae never seen or read his book, but it is said to be the first book to use symbols to identify elements. The name Dalton was also usedin the weight of atomic units Examplehearing someone sayits 230 daltons.

∙ 13y agoIn 1803 Dalton proposed an atomic theory. He discovered that all matter is made of tiny indivisible particles called atoms. He also discovered that all atoms of an element are alike and that atoms combine in simple ratios to make compounds.

Is Dalton's atomic theory the same as the particle theory?
No b/c Thomson discovered that atoms can be cut. He found this out while studying rays traveling between charged metal plates in a vacuum tube. He discovered that the rays were consisted of negatively charged particles. He had just discovered electrons. He discovered all of this on a trip from America. Since electrons are so small, he believed that they could only be from inside of the atom. Since Thomson's discovery of the electron, John Dalton's theory that atoms are indivisible had to be changed.
How the first atomic theory was formed?
john dalton develop an atomic theory in 1803, based on idea of the atomic exsiting
What is the first theory to relate chemical changes to events at the atomic level?
Dalton's Atomic Theory
Whose ideas led to the atomic theory of matter?
The idea that led to the atomic theory of matter, was John Dalton.
Why was Dalton's model of the atom changed after Thomson's experiment?
John Dalton's atomic theory indicated that atoms were indivisible spheres. When JJ Thomson did his work with cathode ray tubes, he discovered that atoms contain electrons, which meant that the atom is not indivisible, that there are smaller particles within.
How did atomic theory lead to the atomic bomb discovery?
the atomic bomb was not discovered, it was invented then built.
Who discovered atomic theory?
well who is it
When did Dalton discovered the atomic theory?
1800's
What were arthur compton's contributions to the atomic theory?
he discovered the electron
What was the date that Niels Bohr discovered atomic theory?
He discovered this in 1764
Why was the atomic theory imoportant when first discovered?
because back then they need other methods of science to create more mothion and so then Democritus thought of the atomic theory.
Who discovered the theory of reletivity?
The theory of relativity was developed by Albert Einstein.
What was Chadwick's contribution to the current atomic theory?
James Chadwick discovered the neutron in 1932.
What were drawback of atomic model discovered by JJ Thomson?
he could not explain the theory properly
What was Rutherford's contributions to the atomic theory?
Ernest Rutherford contributed to the atomic theory through his gold foil experiment. He discovered that there was a positively charged central core to the atom and he called it the nucleus.

What year did Niels Bohr proved his atomic theory?
Niels Bohr published his atomic theory in 1913...which applied Max Planck's quantum theory to Rutherford's idea of a nuclear structure.... adding the idea of electrons traveling in orbitsaround the atom's nucleus.
