well who is it
the atomic bomb was not discovered, it was invented then built.
James Chadwick discovered the neutron in 1932.
ATOMIC NUMBER YEAR IN WHICH IT WAS DISCOVERED? it was discovered in 1913 by British physicist Henry Mosely
Democritus achievements are his atomic theory and his book -on the little order of the world- which describes his atomic theory.
The ancient Greeks did not perform any experiments to test the atomic theory proposed by Democritus. To the ancient Greeks the atomic theory was a part of philosophy, not science.
the atomic bomb was not discovered, it was invented then built.
1800's
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.
because back then they need other methods of science to create more mothion and so then Democritus thought of the atomic theory.
Albert Einstein discovered the theory of relativity and is known for this famous equation E=MC2 which was used to create atomic bombs..
James Chadwick discovered the neutron in 1932.
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.
Atoms are made up of smaller particles.
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.
She discovered that different atoms give off different frequencies of light.
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.
Lavoisier is not known for an atomic theory.
