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.
Einstein built on the work of Max Planck, who introduced the concept of quantization of energy. Einstein also referenced the photoelectric effect experiments by Philipp Lenard and Heinrich Hertz. These scientists' work helped Einstein develop his theory of the quantization of light and the photon concept.
In Dalton's theory the electrons in the atom travel in a one layered orbital rotation around the nucleus, in the modern, or electron cloud, theory the electrons travel in a more radical patterned movement while still staying in their respected energy levels.
The scientist who first introduced the atomic theory was John Dalton in the early 19th century. Dalton's atomic theory proposed that all matter is made up of tiny, indivisible particles called atoms, each with its own unique properties. His work laid the foundation for modern atomic theory.
The development of the atomic theory is primarily attributed to the ancient Greek philosopher Democritus. He proposed that all matter is made up of tiny, indivisible particles called atoms. His ideas laid the foundation for modern atomic theory.
The atomic theory is a scientific theory because it is based on observable evidence and experimentation. It provides a framework for understanding the behavior of matter at the atomic and subatomic levels, and it has been supported by numerous experiments and observations in physics and chemistry over the years.
he did not develop anything regarding the 'atomic theory' for he was against that theory.
1955
He developed the "ELECTOMAGNETISM"
discovering artificial radioactivity
he drew pictures about it :) <3
he came up with the theory of atomic numbers
Im sorry 4 not being completely sure, but................. Newton believed in atomic forces. He thought that atoms and atomic power could not be properly understood without the use of quantum mechanics. -Sorry TJ

Aristotle rejected the concept of atoms and instead proposed a continuous, indivisible substance as the basis of all matter. His views on the composition of matter were influential for many centuries, until the development of modern atomic theory in the 19th century.
trololol...hahahaXD stop cheatin:P get your own answer.haha
Democritus contributed to the atomic theory around 400 BC. He proposed that all matter is composed of indivisible particles called atoms.
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.
