Leucippus is a mysterious figure whose exact dates are unknown - some say he never existed - but is still considered the be the founder of the Atomistic theory. Democritus was born 460 B.C. and died 370 B.C. He was a disciple of Leucippus and both men are credited with the atomistic theory.
the atomic bomb was not discovered, it was invented then built.
well who is it
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.
