john dalton developed the atomic theory , which he published in 1803
What else can I help you with?
Which is not part of John Dalton atomic theory?
Atoms are made up of smaller particles.
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.
Whose ideas led to the atomic theory of matter?
The atomic theory of matter can be attributed to the ideas proposed by the ancient Greek philosopher Democritus. He hypothesized that all matter is composed of indivisible and indestructible particles called atoms, which differ in shape, size, and arrangement. Democritus' atomic theory laid the foundation for modern atomic theory.
What is the atomic number for manganese?
The atomic number for Manganese is 25. It was discovered in 1774 so was one of the earlier elements discovered. It has a melting point of 1519 Kelvin.
How did Thomson's discovery change Dalton's atomic theory?
Thomson discovered that atoms can be cut. He found this out while studying rays traveling between charged metal plates in a vacuum tube.

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 was the date that Niels Bohr discovered atomic theory?
Niels Bohr's atomic theory, known as the Bohr model, was proposed in 1913. This theory revolutionized our understanding of atomic structure by introducing the concept of quantized energy levels within the atom.
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?
Albert Einstein discovered the theory of relativity and is known for this famous equation E=MC2 which was used to create atomic bombs..
What was Chadwick's contribution to the current atomic theory?
James Chadwick discovered the neutron in 1932.
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 did Annie Jump Cannon contribute to the atomic theory?
She discovered that different atoms give off different frequencies of light.
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.
