The atomic theory that was supported by Mendeleev when scientist found the elements that Mendeleev predicted was out there in the world. When Mendeleev made the Periodic Table he left spots for elements he did not have but knew would be found one day.
FOUND THE ELEMENTS HE
PREDICTED*** (I got this answer right on my test, you out too!)

John Dalton.. :))
Louis de Broglie
Yes, John Dalton was an English chemist, meteorologist and physicist. He is best known for his pioneering work in the development of modern atomic theory, and his research into color blindness.
The Atomic Theory
The scientist that designed the atomic theory is Thomas Jefferson.
They didn't help with atomic theory, they created it.
Lynn Margulis ;)
In 1869, Dmitri Mendeleev listed the elements in order of increasing atomic weight and grouped elements that seemed to have similar chemical reactions.
mitchell creech
Mendeleeve formulated the Table of the Elements by listing them by their atomic weight and grouping them into 'families', with similar characteristics.

The third principle of Dalton atomic theory is no supported.
John Dalton
there were many scientists that contributed towards it but Joseph j. Thomson, Hans geiger, ernest marsden. ernest Rutherford, Henry moseley and James chadwick all made key discoveries and are the main scientists behind the theory.Alfred Nobel,Mendeleev and Neil Bhorbecause theire are the great scientistChadwick explain the atomic theoryniels hendrik bohrmitchell creech
Probably Neils Bohr
