Benjamin Franklin's contribution to the atomic theory was his proposal that electricity was a fundamental force that could be understood through atomic models. He conducted experiments with electricity and proposed the idea of positive and negative charges, which later contributed to the development of the atomic theory.
He determined the number of positive charges in the nucleus of an atom. He was the first one to bring the concept of atomic number.
Neil bohr has done research in quantum mechanics.
Joseph Lucas is not primarily known for contributions to atomic theory; rather, he was an English inventor and industrialist associated with the automotive and electrical industries. The development of atomic theory is more commonly attributed to scientists such as John Dalton, J.J. Thomson, and Niels Bohr. If you meant another figure or are looking for information on a different aspect of atomic theory, please clarify!
Michael Faraday's main contribution to atomic theory was his work on electrolysis, which demonstrated that chemical compounds are composed of discrete particles and that these particles carry an electric charge. This provided evidence for the existence of atoms and laid the foundation for the development of the modern atomic theory.
Eugen Goldstein's atomic theory was not entirely correct. He proposed the existence of a positively charged particle known as the "proton," which was a significant contribution to the understanding of atomic structure. However, his theory also included the idea of "cathode rays" being composed of a new form of matter, which was later disproven.
Any atomic theory from B. Franklin.

Antoine Lavoisier was a French nobleman and chemist. His contribution to the development of the modern atomic theory was his idea of the possibility of an Atomic Mass.
The most important contribution of Werner Heisenberg was the discovery of the uncertainty principle.

The contribution of anyone prior to about 1600 to the development of atomic theory might as well be "nothing whatsoever." Democritus and/or Leucippus contributed the name "atomos", but not much else; they were wrong about nearly every detail. John Dalton is just about the earliest scientist to have had any significant contribution to atomic theory, and most of what we now consider atomic theory was developed since about 1900.
he helped the creator of electrons and the studier of chemistry
James Chadwick discovered the neutron in 1932.
Mendeleeve formulated the Table of the Elements by listing them by their atomic weight and grouping them into 'families', with similar characteristics.
Benjamin Franklin made several contributions to various scientific fields. In atomic theory, he was the first to propose how to measure the size of an atom.
