He contriubuted to modern science with his model for atomic theory which he described was similar to the rings of saturn and he descibed that in his model of atomic theory. Hantaro Nagaoka was a great man and and he contributed alot of tings to modern science i cant name them all but he contributed alot of things to modern science
John Dalton first pursued research into atomic theory. He was the first person to propose the existence of the atomic structure.
john dalton developed the atomic theory , which he published in 1803
In terms of atomic theory the protons and electroncs contribute the charge to an atom. In terms of quantum theory electrons are a type of lepton and protons are composed of quarks. So quarks and leptons contribute nuclear charge.
Scientists had made observations that did not fit exactly with Dalton's theory. Scientists changed the atomic theory to include this new knowledge. While the modern atomic theory is based on Dalton's theory, it is also very different.
Any theory which involves things orbiting round a central object. Such as the early theory of atomic structure.
He started working on the atomic theory in 1892. He developed the Saturnian Model in 1904.
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
trololol...hahahaXD stop cheatin:P get your own answer.haha
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.
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.
Democritus contributed to the atomic theory around 400 BC. He proposed that all matter is composed of indivisible particles called atoms.
