Leukippus, Democritus, Dalton, Bohr, Rutherford, Thomson and many others.
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.
Theodore Schwann, Matthias Schlieden, Rudolph Virchow. They all made very important contributions to the cell theory.
Many philosophers have made contributions, such as Pythagoras, who made the Pythagorean theory, which is talking about angles such as a right angle and making that into an equation.
Emanouil Atanassov is a Bulgarian mathematician known for his work in the field of algebra and number theory. He has made significant contributions to the study of algebraic structures and their applications in cryptography and coding theory. Atanassov's research has advanced our understanding of abstract algebra and its practical implications in modern technology.
Democritus achievements are his atomic theory and his book -on the little order of the world- which describes his atomic theory.
One scientist who made important contributions to atomic theory is John Dalton. He is known for his work on the atomic theory of matter, proposing that all matter is made up of tiny, indivisible particles called atoms. His ideas laid the foundation for modern chemistry.
Thales was not a chemist; important contributions in geometry and astronomy.
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.
Early scientists who made significant contributions to the development of the atomic theory include Democritus, who proposed that matter is made up of indivisible particles called atoms, and John Dalton, who introduced the concept that elements are made up of identical atoms that combine to form compounds in fixed ratios.
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.
Arthur Compton made significant contributions to the atomic theory by discovering the Compton effect, which provided experimental evidence for the particle nature of light. This discovery helped establish the understanding that light can behave as both a wave and a particle, which was fundamental to the development of quantum mechanics.
the element carbon is made up of carbon and nitrogen
Philipp Lenard made contributions to understanding the photoelectric effect, for which he was awarded the Nobel Prize in Physics in 1905. However, he did not contribute significantly to the development of the atomic theory. His work focused more on experimental physics and electron behavior rather than atomic structure.
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.
Yes, James Chadwick was a British physicist who made significant contributions to the atomic theory. He is best known for his discovery of the neutron, a neutral subatomic particle found in the nucleus of an atom. This discovery helped to advance our understanding of atomic structure and laid the foundation for the development of nuclear physics.
Robert A. Millikan was the first to determine the electrical charge of the electron.
Neils Bohr was a Danish physicist. He made contributions to the understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922.
