Aristotle held the view that there were five elements: fire, water, air, earth, Aether. Fire was hot. Water was wet. Air was light. Earth was cool and heavy. Aether was divine. Aristotle has since been proven wrong in this area because we have zoomed in and broadened our views of the elements.
Mendeleev's contribution to the atomic theory was published in 1869 in his book "Principles of Chemistry." In this work, he introduced the periodic table of elements, organizing them by atomic weight and properties, and leaving gaps for undiscovered elements.
The atomic theory of matter can be attributed to the ideas proposed by the ancient Greek philosopher Democritus. He hypothesized that all matter is composed of indivisible and indestructible particles called atoms, which differ in shape, size, and arrangement. Democritus' atomic theory laid the foundation for modern atomic theory.
His atomic theory. He was the one who thought that there were atoms in everything.
Democritus, an ancient Greek philosopher, is known for proposing the concept of atomism - the idea that all matter is made up of tiny, indivisible particles called atoms. His ideas laid the foundation for modern atomic theory and influenced the development of scientific thought in fields such as chemistry and physics.
Chemists benefited from Dalton's atomic theory by gaining a better understanding of the composition and behavior of matter at the atomic level. This theory provided a foundation for modern chemistry and helped explain various chemical reactions and properties of elements.

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.
The most important contribution of Werner Heisenberg was the discovery of the uncertainty principle.
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 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.
